Summary

RAB15 (RAB15, member RAS oncogene family, HGNC:20150) is a protein-coding gene on chromosome 14q23.3, encoding Ras-related protein Rab-15 (P59190). The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes.

Enables G protein activity. Involved in positive regulation of regulated secretory pathway and receptor-mediated endocytosis. Located in cilium; endosome membrane; and perinuclear region of cytoplasm.

Function. The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different sets of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. RAB15 may act in concert with RAB3A in regulating aspects of synaptic vesicle membrane flow within the nerve terminal.

Subunit / interactions. The GTP bound form of RAB15 interacts with REP15. Interacts (GTP-bound form) with MICAL1, MICAL3, MICALCL, EHBP1 and EHBP1L1.

Subcellular location. Cell membrane.

Activity regulation. Regulated by guanine nucleotide exchange factors (GEFs) which promote the exchange of bound GDP for free GTP. Regulated by GTPase activating proteins (GAPs) which increase the GTP hydrolysis activity. Inhibited by GDP dissociation inhibitors (GDIs).

Domain organisation. Switch 1, switch 2 and the interswitch regions are characteristic of Rab GTPases and mediate the interactions with Rab downstream effectors. The switch regions undergo conformational changes upon nucleotide binding which drives interaction with specific sets of effector proteins, with most effectors only binding to GTP-bound Rab.

Similarity. Belongs to the small GTPase superfamily. Rab family.
