A PF09069 EF-hand_3 EF-hand Domain Members 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].

A PF09068 EF-hand_2 EF hand Domain Members 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]. PFAM PF09068
A PF00397 WW WW domain Domain The WW domain is a protein module with two highly conserved tryptophans that binds proline-rich peptide motifs in vitro. PFAM PF00397
