PF09069EF-hand (EF-hand_3)EF-handMembers of this family adopt a helix-loop-helix motif, as per other EF hand domains.

However, since they do not contain the canonical pattern of calcium binding residues found in many EF hand domains, they do not bind calcium ions. The main function of this domain is the provision of specificity in beta-dystroglycan recognition, though in dystrophin it serves an additional role: stabilisation of the WW domain (Pfam:PF00397), enhancing dystroglycan binding [1].
Domain
PF00569Zinc finger, ZZ type (ZZ)Zinc finger, ZZ typeZinc finger present in dystrophin, CBP/p300. ZZ in dystrophin binds calmodulin. Putative zinc finger; binding not yet shown. Four to six cysteine residues in its sequence are responsible for coordinating zinc ions, to reinforce the structure [2]. Domain

They are expressed in the skeletal, cardiac and smooth muscle. Although numerous studies have been conducted on the sarcoglycan subcomplex in skeletal and cardiac muscle, the manner of the distribution and localisation of these proteins along the nonjunctional sarcolemma is not clear [1]. This family contains alpha and epsilon members. This entry represents the N-terminal domain.

Although numerous studies have been conducted on the sarcoglycan subcomplex in skeletal and cardiac muscle, the manner of the distribution and localisation of these proteins along the nonjunctional sarcolemma is not clear [1]. This family contains alpha and epsilon members and represents the second domain which has an Ig-like fold.
