Dystroglycans are essential elements of the neuromuscular junction (NMJ). The gene for dystroglycan is expressed as a precursor protein that is post-translationally cleaved into a 156 kDa extracellular peripheral membrane protein called α-dystroglycan and a 43 kDa transmembrane protein, β-Dystroglycan. The latter protein contains a PPxY motif that promotes binding to WW domain-containing proteins, such as utrophin and dystrophin. Phosphorylation at tyrosine 892 within the PPxY motif may regulate c-Src interactions with β-Dystroglycan, as well as inhibit interactions with WW domain proteins. In skeletal muscle, β-Dystroglycan is normally localized to the plasma membrane, however phosphorylation of Tyr-892 leads to localization of β-Dystroglycan to endosomal compartments along with c-Src. Thus, phosphorylation at Tyr-892 may have important roles in altering the localization of β-Dystroglycan during NMJ formation.

Western blot analysis of HepG2 cells untreated (lanes 1 & 3) or treated with pervanadate (1 mM) for 30 min (lanes 2 & 4). Blots were probed with anti-β-Dystroglycan (lanes 1 & 2) and anti-β-Dystroglycan (Tyr-892) (lanes 3 & 4).

Clone (M205) was generated from a recombinant protein corresponding to the C-terminal region of human β-Dystroglycan. This sequence has high homology to the conserved region in mouse, cow, and rabbit β-Dystroglycan.
