S100G(redirected from S100 calcium-binding protein G)
S100GA gene on chromosome Xp22.2 that encodes calbindin-D9K, a cytosolic vitamin D-dependent calcium-binding protein, which contains 2 active calcium-binding domains. Calbindin D9K’s expression correlates with calcium transport activity; it may increase Ca2+ absorption by buffering Ca2+ in the cytoplasm and increase ATP-dependent Ca2+ transport in duodenal basolateral membrane vesicles.
