Summary: Predicted to enable several functions, including GDP binding activity; GTPase activity; and TPR domain binding activity. Predicted to be involved in several processes, including endocytic recycling; positive regulation of corticotropin secretion; and protein import into peroxisome membrane. Located in mitochondrion. Is expressed in brain; liver; and small intestine. Orthologous to human RAB8B (RAB8B, member RAS oncogene family). [provided by Alliance of Genome Resources, Dec 2024]

Rab8b is involved in trafficking of WNV particles from recycling endosomes to the plasma membrane.
Title: Rab8b Regulates Transport of West Nile Virus Particles from Recycling Endosomes.
Simultaneous loss of Rab8a and Rab8b has little effect on ciliogenesis, whereas additional loss of Rab10 greatly affects ciliogenesis.
Title: Rab8a and Rab8b are essential for several apical transport pathways but insufficient for ciliogenesis.
Rab8b siRNA diminished autophagic killing of BCG, reduced the number of LC3 puncta in a high-content imaging analysis of cells stably expressing fluorescent protein fusion with LC3 and impeded basal clearance of the autophagic adaptor p62.

Otoferlin-Rab8b interaction links otoferlin to the basolateral endocytic and secretory trafficking.
Title: Rab8b GTPase, a protein transport regulator, is an interacting partner of otoferlin, defective in a human autosomal recessive deafness form.
These results suggest that the interaction of JRAB/MICAL-L2 with Rab8 and Rab13 coordinates the assembly of tight junctions and adherens junctions.

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.
