View in BioMuta


RAB13 is a member of the Rab family of small G proteins and plays a role in regulating membrane trafficking between trans-Golgi network (TGN) and recycling endosomes (RE). RAB13 is thought to participate in polarized transport, in the assembly and/or the activity of tight junctions, which are components of the apical junctional complex (AJC) of epithelial cells. There are several alternatively spliced transcript variants for this gene, and a pseudogene located on chromosome 12.
