Background:  The family of EF-hand type Ca2+-binding proteins includes Calbindin (previously designated vitamin D-dependent Ca2+-binding protein), Calbindin D9K, S-100 α and β, Calgranulins A (also designated MRP8), B (also designated MRP14) and C, and the parvalbumin family members, including parvalbumin α and parvalbumin β (also designated oncomodulin). The gene encoding human Calbindin D9K is located on the X-chromosome and consists of three exons and contains four Alu repeats. Calbindin D9K protein is present in cartilage, bone and certain teeth, such as the ameloblasts of incisors and molars. In addition, Calbindin D9K mRNA is detected in proximal small intestine, but not in human kidney, uterus or placenta (however, the protein is present in these tissues in other species). Rat Calbindin D9K binds the estrogen receptor because the gene encoding contains an estrogen response element downstream from its promoter. In contrast, the homologous human sequence differs by two essential nucleotides and does not bind the estrogen receptor, suggesting that this change suppresses gene expression in human tissues, such as uterus and possibly placenta.
