Also known as: anon-WO02059370.56; cg6647; CG6647; Dmel\CG6647; DmPorin1; DmVDAC; DVDAC; l(2)k05123; POR-1; Porin; PORIN; Vdac; VDAC; Vdac1; VDAC1
Summary: Enables voltage-gated monoatomic anion channel activity. Involved in several processes, including negative regulation of calcium import into the mitochondrion; sperm individualization; and sperm mitochondrion organization. Located in Nebenkern and mitochondrion. Is active in mitochondrial outer membrane. Is expressed in several structures, including follicle cell; gonad; head epidermis primordium; mesoderm; and visceral muscle primordium. Used to study retinal degeneration. Human ortholog(s) of this gene implicated in prostate cancer. Orthologous to several human genes including VDAC1 (voltage dependent anion channel 1) and VDAC2 (voltage dependent anion channel 2).
