Mouse Integrin  alpha 11 Antibody

Integrin alpha 11 ( ITGA11) is a 155-160 kDa member of the integrin alpha chain family of molecules. It preferentially forms a cell surface heterodimer with beta 1 Integrin. In particular, it is further classified as a collagen-binding group member, showing a preference for binding to collagen I and II, plus group A Streptococcal Scl1 protein. ITGA11 is expressed by embryonic mesenchymal cells in areas that incorporate collagen during development. In adult tissue, fibroblasts express ITGA11, and a collagen:ITGA11 interaction likely contributes to the formation of myofibroblasts. Mature mouse ITGA11 is an 1166 amino acid (aa) type I transmembrane glycoprotein. It contains a large 1119 aa extracellular domain (ECD) (aa 23-1141) plus a short 24 aa cytoplasmic region. The ECD shows 7 x 60 aa FG-Gap repeats that generate beta -propellers (aa 24-650) with an intervening I domain that binds collagen (aa 164-345). There is one potential splice variant that shows an eight aa substitution for aa 89-119 coupled to a seven aa insertion after Gly690. Over aa 23-1141, mouse ITGA11 shares 95% and 90% aa identity with rat and human ITGA11, respectively.
