PubMed PubMed Product Detail Members of the RAB protein family, such as RAB1B, are low molecular mass monomeric GTPases localized on the cytoplasmic surfaces of distinct membrane-bound organelles. 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]
Function:
Protein transport. Regulates vesicular transport between the endoplasmic reticulum and successive Golgi compartments.
Subcellular Location:
Membrane. Cytoplasm. Targeted by REP1 to membranes of specific subcellular compartments including endoplasmic reticulum, Golgi apparatus, and intermediate vesicles between these two compartments. In the GDP-form, colocalizes with GDI in the cytoplasm.
Post-translational modifications:
Prenylated; by GGTase II, only after interaction of the substrate with Rab escort protein 1 (REP1). AMPylation at Tyr-77 occurs in the switch 2 region and leads to moderate inactivation of the GTPase activity. It appears to prolong the lifetime of the GTP state of RAB1B by restricting access of GTPase effectors to switch 2 and blocking effector-stimulated GTP hydrolysis, thereby rendering RAB1B constitutively active.
Similarity:
Belongs to the small GTPase superfamily. Rab family.
