Synj2bp - synaptojanin 2 binding protein

Enables type II activin receptor binding activity. Involved in positive regulation of protein localization to cell surface; positive regulation of receptor internalization; and regulation of activin receptor signaling pathway. Acts upstream of or within Rho protein signal transduction; protein targeting; and regulation of endocytosis. Located in cell surface. Is expressed in several structures, including blood vessel; extraembryonic component; genitourinary system; neural tube; and retina. Orthologous to human SYNJ2BP (synaptojanin 2 binding protein).
