Function
CALM_BOVIN Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases. Together with CEP110 and centrin, is involved in a genetic pathway that regulates the centrosome cycle and progression through cytokinesis (By similarity).

Publication Abstract from PubMed
Fragment TR2C is the C-terminal part of the calcium-binding protein calmodulin, including residues 78-148. The crystal structure of TR2C was solved by molecular replacement and refined to a conventional R value of 21.8% (R(free) = 22.0%), using all data in the resolution range 20.0-1.7 A. This study shows that the secondary structure of TR2C, a pair of EF-hand motifs with two calcium-binding sites, is similar to the corresponding motifs in intact calmodulin. However, it also indicates that the N-terminus of helix E is closer to the C-terminus of helix H in TR2C than in the intact protein and that the loop connecting the EF-hands shows different conformations in the two structures. The crystal structure of TR2C was further found to be similar to the set of NMR structures of this fragment, although some pronounced differences exist.
