The Human GCAP1 and GCAP2 Genes Are Arranged in a Tail
... GCAPs are members of the large and diverse superfamily of calmodulin-like Ca2/-binding proteins (Nakayama et al., 1992) that evolved from a common ancestor containing four EF-hand consensus sequences. The amino acid sequences of GCAP1 and GCAP2 predict three EF-hand Ca2/-binding consensus sequences ...
