Calmodulin/Calcineurin/KChIP (CaCa) Superfamily

This superfamily includes Calcium binding domains and proteins of about 220 aas. Many proteins in the Phox family (5.B.1) have N-terminal domains of about 220 aas that are homologous to the members of The Calmodulin Calcium Binding Protein (Calmodulin) Family (TC# 8.A.82) as well as the Mitochondrial EF Hand Ca2+ Uniporter Regulator (MICU) Family (TC# 8.A.44). Other proteins bearing this domain include Mitochondrial Carriers (TC# 2.A.29.23.1, 8 and 9) and the Programmed Cell Death 8 protein (O75340; TC# 3.A.5.9.1).
