蛋白结构（Molecular Characterization）
Cynomolgus ITGA7X1B&ITGB1 Heterodimer Protein, Tag Free&His Tag, produced by co-expression of ITGA7X1B and ITGB1, has a calculated MW of 115.1 kDa (ITGA7X1B) and 85.0 kDa (ITGB1). Subunit ITGA7X1B contains no tag but an acidic tail at the C-terminus and subunit ITGB1 contains a polyhistidine tag and a basic tail at the C-terminus. The non-reducing (NR) protein migrates as 95-115 kDa due to glycosylation.

Report
背景（Background）
Integrin alpha-7/beta-1 is the primary laminin receptor on skeletal myoblasts and adult myofibers, which is highly expressed in cardiac muscle, skeletal muscle and smooth muscle cells, and localizes to Z-disc and costamere structures. It is involved in the maintenance of the myofibers cytoarchitecture as well as for their anchorage, viability and functional integrity. Isoform Alpha-7X2B and isoform Alpha-7X1B promote myoblast migration on laminin 1 and laminin 2/4, but isoform Alpha-7X1B is less active on laminin 1 (In vitro). ITGA7 has been shown to interact with Merosin, ITGB1, FHL2 and FHL3.
