A PF00036 EF-hand_1 EF hand Domain The EF-hands can be divided into two classes: signaling proteins and buffering/transport proteins. The first group is the largest and includes the most well-known members of the family such as calmodulin, troponin C and S100B. These proteins typically undergo a calcium-dependent conformational change which opens a target binding site. The latter group is represented by calbindin D9k and do not undergo calcium dependent conformational changes. PFAM PF00036
