Background
The protein encoded by this gene plays a direct regulatory role in calcium-ion-dependent exocytosis in both endocrine and exocrine cells and plays a key role in insulin secretion by pancreatic cells. This gene is likely a tumor suppressor. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jun 2010],
Function
domain:The N-terminus of the RabBD domain is necessary and sufficient for interaction with RAB27A.,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.,similarity:Contains 1 FYVE-type zinc finger.,similarity:Contains 1 RabBD (Rab-binding) domain.,subcellular location:Recruited to the vesicle membrane in a GTP-and RAB3B-dependent manner 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.,tissue specificity:Moderate to high levels of expression in thyroid, ovary, stomach, heart, pancreas, skeletal muscle, kidney and liver. Also detected in epithelial cells.,
