  • 功能
    Protein transport. Regulates vesicular transport between the endoplasmic reticulum and successive Golgi compartments.
  • 序列相似性
    Belongs to the small GTPase superfamily. Rab family.
  • 翻译后修饰
    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.
  • 细胞定位
    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.
  • Information by UniProt
