RAB1B functions in the early secretory pathway and is essential for vesicle transport between the endoplasmic reticulum (ER) and Golgi (Chen et al., 1997 [PubMed 9030196]; Alvarez et al., 2003 [PubMed 12802079]).[supplied by OMIM, Jan 2009] Expression Ubiquitous expression in prostate (RPKM 64.5), fat (RPKM 64.0) and 25 other tissues See more Orthologs mouse all
