FunctionMay function as calcium sensor and modulator, contributing to cellular calcium signaling. May function by interacting with other proteins, such as TPR-containing proteins, and indirectly play a role in many physiological processes such as the reorganization of the actin cytoskeleton and in cell motility. Binds 2 calcium ions. Calcium binding is cooperative.
Sequence similaritiesBelongs to the S-100 family. Contains 2 EF-hand domains.
Post-translational modificationsThe N-terminus is blocked.
