Also Known as WARBM3; RAB18LI1

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 22931

About RAB18

Cytogenetic location: 10p12.1 Genomic coordinates (GRCh38): 10:27,504,304-27,542,239 (from NCBI)

This gene has 45 transcripts (splice variants), 183 orthologues, 68 paralogues and is associated with 3 phenotypes. Ubiquitous expression in adrenal (RPKM 23.5), brain (RPKM 23.2) and 25 other tissues.

Summary

The protein encoded by this gene is a member of a family of Ras-related small GTPases that regulate membrane trafficking in organelles and transport vesicles. Knockdown studies is zebrafish suggest that this protein may have a role in eye and brain development. Mutations in this gene are associated with Warburg micro syndrome type 3. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012]
