Dystroglycan (Dystrophin-associated glycoprotein 1); Dystroglycan is one of the dystrophin-associated glycoproteins, which is encoded by a 5.5 kb transcript in human. The protein product is cleaved into two non-covalently associated subunits, [alpha] (N-terminal) and [beta] (C-terminal). In skeletal muscle the dystroglycan complex works as a transmembrane linkage between the extracellular matrix and the cytoskeleton. [alpha]-dystroglycan is extracellular and binds to merosin ([alpha]-2 laminin) in the basement membrane, while [beta]-dystroglycan is a transmembrane protein and binds to dystrophin, which is a large rod-like cytoskeletal protein, absent in Duchenne muscular dystrophy patients. Dystrophin binds to intracellular actin cables. In this way, the dystroglycan complex, which links the extracellular matrix to the intracellular actin cables, is thought to provide structural integrity in muscle tissues. The dystroglycan complex is also known to serve as an agrin receptor in muscle, where it may regulate agrin-induced acetylcholine receptor clustering at the neuromuscular junction. There is also evidence which suggests the function of dystroglycan as a part of the signal transduction pathway because it is shown that Grb2, a mediator of the Ras-related signal pathway, can interact with the cytoplasmic domain of dystroglycan. In general, aberrant expression of dystrophin-associated protein complex underlies the pathogenesis of Duchenne muscular dystrophy, Becker muscular dystrophy and severe childhood autosomal recessive muscular dystrophy. Interestingly, no genetic disease has been described for either [alpha]- or [beta]-dystroglycan. Dystroglycan is widely distributed in non-muscle tissues as well as in muscle tissues. During epithelial morphogenesis of kidney, the dystroglycan complex is shown to act as a receptor for the basement membrane. Dystroglycan expression in mouse brain and neural retina has also been reported. However, the physiological role of dystroglycan in non-muscle tissues has remained unclear. : Pssm-ID: 461655 Cd Length: 290 Bit Score: 480.26 E-value: 3.02e-164

Alpha-Dystroglycan N-terminal domain 2; 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. 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. : Pssm-ID: 465761 Cd Length: 123 Bit Score: 244.02 E-value: 2.60e-76

They play numerous roles in cell fate, signalling, proliferation, differentiation, and migration; members include E-, N-, P-, T-, VE-, CNR-, proto-, and FAT-family cadherin, desmocollin, and desmoglein, a large variety of domain architectures with varying repeat copy numbers. Cadherin-repeat containing proteins exist as monomers, homodimers, or heterodimers. This family also includes the cadherin-like repeats of extracellular alpha-dystroglycan.
