B PF09042 Titin_Z Titin Z Domain The titin Z domain, that recognises and binds to the C-terminal calmodulin-like domain of alpha-actinin-2 (Act-EF34), adopts a helical structure, and binds in a groove formed by the two planes between the helix pairs of Act-EF34. This interaction is essential for sarcomere assembly [1]. PFAM PF09042
A PF08726 EFhand_Ca_insen Ca2+ insensitive EF hand Domain EF hands are helix-loop-helix binding motifs involved in the regulation of many cellular processes. EF hands usually bind to Ca2+ ions which causes a major conformational change that allows the protein to interact with its designated targets. This domain corresponds to an EF hand which has partially or entirely lost its calcium-binding properties. The calcium insensitive EF hand is still able to mediate protein-protein recognition [1].
