background:
Rab GTPase effector involved in the late steps of regulated exocytosis, both in endocrine and exocrine cells (By similarity). Acts as a potential RAB3B effector protein in epithelial cells.
Function:
Rab GTPase effector involved in the late steps of regulated exocytosis, both in endocrine and exocrine cells (By similarity). Acts as a potential RAB3B effector protein in epithelial cells.
Subunit:
Recruited to dense-core vesicles through specific interaction with RAB27A in endocrine cells. Interacts with RAB3A, RAB3B, RAB3C and RAB3D. Interacts with ZYX.
Subcellular Location:
Cytoplasm. Cytoplasmic vesicle, secretory vesicle membrane. Recruited to the vesicle membrane in a GTP-and RAB3B-dependent manner in epithelial cells.
Tissue Specificity:
Moderate to high levels of expression in thyroid, ovary, stomach, heart, pancreas, skeletal muscle, kidney and liver. Also detected in epithelial cells.
Similarity:
Contains 1 FYVE-type zinc finger.
Contains 1 RabBD (Rab-binding) domain.
Database links:
UniProtKB/Swiss-Prot: Q9UNE2.1
