RAB3IP Proteins and Enzymes

RAB3IP, also known as Rab-3A-interacting protein, is a 53 kDa 476 amino acid protein with 8 isoforms produced by alternative splicing. The primary function of RAB3IP is to change GDP proteins into GTP proteins. Current research on RAB3IP is being conducted in relation to vitelliform, macular dystrophy, pilocytic astrocytoma, anaplastic astrocytoma and astrocytoma. RAB3IP is linked to the vesicle docking, metaphase, exocytosis, mitosis, transport, synaptic transmission and cytokinesis pathways where it interacts with RAB3IL1, SSX2B, SSX2, RAB8A and RAB3A.
