The germ cell nuclear factor (GCNF), also known as RTR (retinoid receptor-related testis-associated receptor) or NR6A1 (nuclear receptor subfamily 6, group A, member 1), is a protein that in humans is encoded by the NR6A1gene.[5][6] GCNF is a member of the nuclear receptor family of intracellulartranscription factors .
Its expression pattern suggests that it may be involved in neurogenesis and germ cell development. The protein can homodimerize and bind DNA, but in vivo targets have not been identified. The gene expresses three alternatively spliced transcript variants.[8]
