The protein contains 200 amino acids for an estimated molecular weight of 22541 Da.

 

The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes (PubMed:21248164). Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion (PubMed:21248164). That Rab is mainly involved in the biosynthetic transport of proteins from the Golgi to the plasma membrane (PubMed:21248164). Regulates, for instance, SLC2A4/GLUT4 glucose transporter-enriched vesicles delivery to the plasma membrane (By similarity). In parallel, it regulates the transport of TLR4, a toll-like receptor to the plasma membrane and therefore may be important for innate immune response (By similarity). Plays also a specific role in asymmetric protein transport to the plasma membrane (PubMed:16641372). In neurons, it is involved in axonogenesis through regulation of vesicular membrane trafficking toward the axonal plasma membrane (By similarity). In epithelial cells, it regulates transport from the Golgi to the basolateral membrane (PubMed:16641372). May play a role in the basolateral recycling pathway and in phagosome maturation (By similarity). May play a role in endoplasmic reticulum dynamics and morphology controlling tubulation along microtubules and tubules fusion (PubMed:23263280). Together with LRRK2, RAB8A, and RILPL1, it regulates ciliogenesis ( (updated: July 31, 2019)

Ras-associated protein rab10; rab10

DESCRIPTION

RAB10 belongs to the RAS (see HRAS; 190020) superfamily of small GTPases. RAB proteins localize to exocytic and endocytic compartments and regulate intracellular vesicle trafficking (Bao et al., 1998).

CLONING

Using degenerate oligonucleotide primers to amplify RAB family members from human skeletal muscle total RNA, Bao et al. (1998) obtained a partial RAB10 clone. The deduced 49-amino acid sequence includes the first 2 GTP-binding regions and effector domain residues that are conserved in RAB proteins. Bao et al. (1998) stated that RAB10 protein localizes to the distal Golgi complex. By searching databases for RAS family members, followed by PCR, He et al. (2002) cloned RAB10. The deduced 200-amino acid RAB10 protein contains 4 highly conserved GTPase motifs and a C-terminal geranylgeranylation motif. Northern blot analysis detected a major transcript of about 4 kb and a smaller minor transcript. Highest expression was detected in heart and skeletal muscle, followed by brain, placenta, lung, liver, kidney, pancreas, testis, and spleen. Low expression was detected in ovary, prostate, and colon, and little to no expression was detected in thymus, small intestine, and leukocytes.

GENE FUNCTION

In muscle and fat cells, insulin (INS; 176730) stimulation activates a signaling cascade that causes intracellular vesicles containing glucose transporter-4 (GLUT4, or SLC2A4; 138190) to translocate to and fuse with the plasma membrane. Using mass spectrometry, Larance et al. (2005) identified Rab10, Rab11 (see RAB11A; 605570), and Rab14 (612673) on Glut4 vesicles from cultured mouse adipocytes. These vesicles also contained the RAB GTPase-activating protein (GAP) As160 (TBC1D4; 612465), suggesting that the RAB proteins may be AS160 substrates. Miinea et al. (2005) found that the purified recombinant GAP domain of human AS160 showed GAP activity with RAB2A (RAB2; 179509), RAB8A (165040), RAB10, and RAB14, but not with 14 other RABs. Immunoblot analysis showed that these RABs associated with Glut4-positive vesicles in mouse adipocytes. Miinea et al. (2005) concluded that AK160 functions as a RAB GAP and that RABs may participate in GLUT4 translocation.

GENE STRUCTURE

He et al. (2002) determined that the RAB10 gene contains 5 exons and spans over 36.7 kb.

MAPPING

By radiation hybrid analysis, He et al. (2002) mapped the RAB10 gene to chromosome 2p23.1-p22.3. Hartz (2009) mapped the RAB10 gene to chromosome 2p23.3 based on an alignment of the RAB10 sequence (GENBANK GenBank AF106681) with the genomic sequence (build 36.1). ... More on the omim web site
