This is the second N-terminal domain found in alpha-Dystroglycan (DG). The murine skeletal muscle N-terminal alpha-DG region, contains two autonomous domains; the first identified as an Ig-like and the second resembling ribosomal RNA-binding proteins [1]. This domain is similar to the small subunit ribosomal protein S6 of Thermus thermophilus (S6 domain). It is suggested that the S6 domain may be of functional relevance for LARGE (like-acetylglucosaminyltransferase) recognition along the alpha-DG maturation pathway [2].

Sarcoglycans are a subcomplex of transmembrane proteins which are part of the dystrophin-glycoprotein complex. 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 and represents the second domain which has an Ig-like fold.
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 ...
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].
Zinc 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].
