RAB1B Proteins and Enzymes

Members of the RAB protein family, such as RAB1B, are low molecular mass monomeric GTPases localized on the cytoplasmicsurfaces of distinct membrane-bound organelles. RAB1B functions in the early secretory pathway and is essential forvesicle transport between the endoplasmic reticulum (ER) and Golgi (Chen et al., 1997 (PubMed 9030196); Alvarez etal., 2003 (PubMed 12802079)).(supplied by OMIM)
