>cd04126 Rab20 Rab20 subfamily. Rab20 is one of several Rab proteins that appear to be restricted in expression to the apical domain of murine polarized epithelial cells. It is expressed on the apical side of polarized kidney tubule and intestinal epithelial cells, and in non-polarized cells. It also localizes to vesico-tubular structures below the apical brush border of renal proximal tubule cells and in the apical region of duodenal epithelial cells. Rab20 has also been shown to colocalize with vacuolar H+-ATPases (V-ATPases) in mouse kidney cells, suggesting a role in the regulation of V-ATPase traffic in specific portions of the nephron. It was also shown to be one of several proteins whose expression is upregulated in human myelodysplastic syndrome (MDS) patients. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bo
