This biomarker is also known as:
  • RAB13, member RAS oncogene family,
  • ras-related protein Rab-13,
  • growth-inhibiting gene 4 protein,
  • RAB13,
  • Cell growth-inhibiting gene 4 protein,
  • RAS-associated protein RAB13,
  • cell growth-inhibiting gene 4 protein,


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.
