Summary: RAB proteins, like RAB8B, are low molecular mass monomeric GTPases that localize on the cytoplasmic surfaces of distinct membrane-bound organelles. RAB proteins function in intracellular vesicle transport by aiding in the docking and/or fusion of vesicles with their target membranes (summary by Chen et al., 1997 [PubMed 9030196]).[supplied by OMIM, Nov 2010]
Expression: Ubiquitous expression in bone marrow (RPKM 21.6), lymph node (RPKM 18.0) and 24 other tissues See more

What's a GeneRIF?

Rab8 GTPase can regulate Klotho-mediated inhibition of Wnt signaling activity by modulating translocation of Klotho onto the cell surface.
Title: Rab8 GTPase regulates Klotho-mediated inhibition of cell growth and progression by directly modulating its surface expression in human non-small cell lung cancer.
there is significant upregulation of RAB8B in patients with rs1986112 GG and AG genotype compared to AA genotype, suggesting a role in schizophrenia development
Title: The rs1986112 Variant is Associated with Increased RAB8B Gene Expression in Schizophrenic Patients.
Rab8A GTPase Ser(111) phosphorylation is not directly regulated by PINK1 in vitro and demonstrate in cells the time course of Ser(111) phosphorylation of Rab8A, 8B and 13 is markedly delayed compared to phosphorylation of Parkin at Ser(65).
Title: Phosphoproteomic screening identifies Rab GTPases as novel downstream targets of PINK1.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
