Functioni

Putative Rab GTPase-activating protein which plays a role in vesicular trafficking (PubMed:28823707). Involved in endosome-to-Golgi trafficking. Acts as a bridging protein by binding simultaneously to golgins, including GOLGA1 and GOLGA4, located at the trans-Golgi, and to the WASH complex, located on endosome-derived vesicles (PubMed:29084197). Plays a role in brain development, including in cortical neuron positioning (By similarity). May also be important for neurite outgrowth, possibly through its involvement in membrane trafficking and cargo delivery, 2 processes that are essential for axonal and dendritic growth (By similarity). May act as a general inhibitor of innate immunity signaling, strongly inhibiting multiple TLR and dectin/CLEC7A-signaling pathways. Does not alter initial activation events, but instead affects maintenance of inflammatory gene expression several hours after bacterial lipopolysaccharide (LPS) challenge (By similarity).By similarity1 Publication

Involvement in diseasei

Pontocerebellar hypoplasia 11 (PCH11)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA non-degenerative form of pontocerebellar hypoplasia, a disorder characterized by structural defects of the pons and cerebellum, evident upon brain imaging. PCH11 features include severely delayed psychomotor development with intellectual disability and poor speech, microcephaly, dysmorphic features, and pontocerebellar hypoplasia. PCH11 inheritance is autosomal recessive.
