- Sen rakenne on RBCC (RING, Bbox1, Bbox2, Coiled-coil) ja C-terminaalin osalta alaluokkaa C_I (FN3, PRY-SPRY).
- Geeni koodaa kahta isoformia. Toisessa, pidemmässä, on 710
aminohappoa (isoformi1). Domeenien sijainnit ovat :
RING( 9..38), Bbox (224..266), Bbox ( 273..398). FN3 domeenit sijoittuvat jaksoon 453..532. SPRY..PRY jakso on 529..700 ja se on samankaltainen myös TRIM67:ssä, joka myös kuuluu tähän alaluokaan C-I .
FN3- domeeni tarkoittaa fibronektiini tyyppi3:n kaltaista domeenia. - TRIM9 proteiini lokalisoituu sytoplasmisiin kappaleisiin. Sen
funktiota ei ollut tunnistettu vielä 2008 mennessä, mutta paljon
artikkelia on kertynyt sen jälkeen. Geeniä ilmenee eniten
aivoissa, sappirakossa ja vielä hieman yhdessä kudoksessa.
Alla on PubMed Gene lähteestä tiedot 1-isoformista, joka on pitempi muoto. Lyhemmästä mudosota on artikkeli, jok selvittää TRIM).n duaalivaikutuksista osuutta antiviraalissa immuunivasteessa. Aivoissa netriini- 1 vaikuttaa olevan tärkeä aksonin kunnolle ja sen signaalijärjestelmään TRIM9 vuorovaikutaa, muta mekanismi ei ole aivan yksinkertaisen selkeä, eikä näihin selityksiin liitetä trimperheen keskeisiä vuorovaikutuksia.

netriini1-reseptorin (DDC) ubikitinaatio pitää aisoissa

Extrasellulaarinen netriini-1 ja sen reseptori DCC edistävät
aivokuoren kehittyvässä neuronissa neuroninjatkeen (aksonin)
haaroittumista. Netriinistä riippuvaa morfogeneesiä edeltää

FAK-aktivaatio js Src-perheen kinaasien aktivoituminen – ja se
lisää exosyyttisten rakkuloiden fuusioitumista- mutta näiden
tapahtumien keskinäinen linkkiytyminen on ollut tuntematon seikka.
Tässä työssä
tutkijat osoittavat, että TRIM9:n tekemä netriinireseptorin (DCC)
ubikitinaatio estää FAK- interaktion ja fosforyloitumisen. Mutta
kun netriini-1 stimuloi tätä reseptoriaan DCC, niin TRIM9 edistää
reseptorin multimerisaatiota, mutta samalla vähenee DCC:n
ubikitinoitumisen aste, mistä taas fokaaliadheesiokinaasin (FAK)
interaktio pääsee edistymään ja samoin sen aktivaatio.
Tutkijat
havaitsivat, että FAK-aktiivisuuden inhibitio ( estäminen)
blokeerasi exosytoosin kohonneet frekvenssit koeputkessa ( in
vitro) ja aksonihaaroittumisen lisääntymisen in vitro ja in
vivo.
Vaikka
fokaaliadheesiokinaasin vähensi SNARE- välitteistä exosytoosia,
SNARE-kompleksien ja rakkuloiden kokoontuminen plasmakalvon

jonkin uuden roolin SNARE-kompleksien kokoontumisen progressiossa

TRIM9-dependent ubiquitination of DCC constrains kinase signaling, exocytosis, and axon branching. Extracellular netrin-1 and its receptor deleted in colorectal cancer (DCC) promote axon branching in developing cortical neurons. Netrin-dependent morphogenesis is preceded by multimerization of DCC, activation of FAK and Src family kinases, and increases in exocytic vesicle fusion, yet how these occurrences are linked is unknown.
-
Here we demonstrate that tripartite motif protein 9 (TRIM9)-dependent ubiquitination of DCC blocks the interaction with and phosphorylation of FAK. Upon netrin-1 stimulation TRIM9 promotes DCC multimerization, but TRIM9-dependent ubiquitination of DCC is reduced, which promotes an interaction with FAK and subsequent FAK activation.
-
We found that inhibition of FAK activity blocks elevated frequencies of exocytosis in vitro and elevated axon branching in vitro and in vivo. Although FAK inhibition decreased soluble N-ethylmaleimide attachment protein receptor (SNARE)-mediated exocytosis, assembled SNARE complexes and vesicles adjacent to the plasma membrane increased, suggesting a novel role for FAK in the progression from assembled SNARE complexes to vesicle fusion in developing murine neurons.

Figure 1. Known TRIM9 interactions. A, In the absence of Netrin-1, TRIM9 inhibits SNAP25 in a ligase-independent manner to inhibit exocytosis. TRIM9 also acts as a filopodia " off " switch by ubiquitinating actin polymerase VASP. Ubiquitinated VASP is dissociated from the ends of actin filaments, leading to decreased actin polymerization. B, When Netrin-1 is present, TRIM9 interacts with Netrin-1 receptor DCC in a ligase-dependent manner. TRIM9's interaction with SNAP25 is inhibited upon Netrin-1 introduction, leading to exocytosis-mediated membrane expansion. TRIM9 ubiquitination of VASP is also inhibited, leading to VASP association with actin filaments, increased actin filament polymerization, and promotion of filopodia formation.

Type I interferon (IFN) is an important component of antiviral innate immune signaling mediated by viral DNA and RNA recognition by the DNA sensor cGAS and RNA sensors RIG-I and MDA5. Activation of these DNA and RNA sensors leads to the recruitment of STING and MAVS, respectively, and converges on TANK-binding kinase 1 (TBK1) signaling for subsequent phosphorylation of IFN regulatory factor 3 (IRF3).

However, the mechanisms that control TBK1 activation are still poorly defined. Here, we identify tripartite motif 9 short isoform (TRIM9s) as a positive regulator in type I IFN signaling. Upon viral infection, TRIM9s undergoes Lys-63-linked auto-polyubiquitination and serves as a platform to bridge GSK3β to TBK1, leading to the activation of IRF3 signaling. Interestingly, we found that TRIM9s selectively inhibits the production of pro-inflammatory cytokines, but enhances the expression of type I IFNs as well as IFN-stimulated genes, in response to viral infection. Our findings reveal novel dual functions of TRIM9s in antiviral immunity, which serve to balance pro-inflammatory response and production of type I IFNs.

- The vertebrate immune response comprises multiple molecular and cellular components that interface to provide defense against pathogens. Because of the dynamic complexity of the immune system and its interdependent innate and adaptive functionality, an understanding of the whole-organism response to pathogen exposure remains unresolved. Zebrafish larvae provide a unique model for overcoming this obstacle, because larvae are protected against pathogens while lacking a functional adaptive immune system during the first few weeks of life. Zebrafish larvae were exposed to immune agonists for various lengths of time, and a microarray transcriptome analysis was executed. This strategy identified known immune response genes, as well as genes with unknown immune function, including the E3 ubiquitin ligase tripartite motif-9 (Trim9). Although trim9 expression was originally described as "brain specific," its expression has been reported in stimulated human Mϕs. In this study, we found elevated levels of trim9 transcripts in vivo in zebrafish Mϕs after immune stimulation. Trim9 has been implicated in axonal migration, and we therefore investigated the impact of Trim9 disruption on Mϕ motility and found that Mϕ chemotaxis and cellular architecture are subsequently impaired in vivo. These results demonstrate that Trim9 mediates cellular movement and migration in Mϕs as well as neurons.

TRIM9-dependent ubiquitination of DCC constrains kinase signaling, exocytosis, and axon branching.

Abstract
Extracellular netrin-1 and its receptor deleted in colorectal cancer (DCC) promote axon branching in developing cortical neurons. Netrin-dependent morphogenesis is preceded by multimerization of DCC, activation of FAK and Src family kinases, and increases in exocytic vesicle fusion, yet how these occurrences are linked is unknown. Here we demonstrate that tripartite motif protein 9 (TRIM9)-dependent ubiquitination of DCC blocks the interaction with and phosphorylation of FAK. Upon netrin-1 stimulation TRIM9 promotes DCC multimerization, but TRIM9-dependent ubiquitination of DCC is reduced, which promotes an interaction with FAK and subsequent FAK activation. We found that inhibition of FAK activity blocks elevated frequencies of exocytosis in vitro and elevated axon branching in vitro and in vivo. Although FAK inhibition decreased soluble N-ethylmaleimide attachment protein receptor (SNARE)-mediated exocytosis, assembled SNARE complexes and vesicles adjacent to the plasma membrane increased, suggesting a novel role for FAK in the progression from assembled SNARE complexes to vesicle fusion in developing murine neurons.Similar articles

Spring, a novel RING finger protein that regulates synaptic vesicle exocytosis.
Li Y1, Chin LS, Weigel C, Li L.Author information
Abstract
The synaptosome-associated protein of 25 kDa (SNAP-25) interacts with syntaxin 1 and vesicle-associated membrane protein 2 (VAMP2) to form a ternary soluble N-ethylmaleimide-sensitive fusion protein attachment protein receptor (SNARE) complex that is essential for synaptic vesicle exocytosis. We report a novel RING finger protein, Spring, that specifically interacts with SNAP-25. Spring is exclusively expressed in brain and is concentrated at synapses. The association of Spring with SNAP-25 abolishes the ability of SNAP-25 to interact with syntaxin 1 and VAMP2 and prevents the assembly of the SNARE complex. Overexpression of Spring or its SNAP-25-interacting domain reduces Ca(2+)-dependent exocytosis from PC12 cells. These results indicate that Spring may act as a regulator of synaptic vesicle exocytosis by controlling the availability of SNAP-25 for the SNARE complex formation.- PMID:
