Human Integrin alpha 3 beta 1 (ITGA3&ITGB1) Heterodimer Protein, His Tag&Tag Free (MALS verified)

Integrin alpha-3/beta-1 is a receptor for fibronectin, laminin, collagen, epiligrin, thrombospondin and CSPG4. Integrin alpha-3/beta-1 provides a docking site for FAP (seprase) at invadopodia plasma membranes in a collagen-dependent manner and hence may participate in the adhesion, formation of invadopodia and matrix degradation processes, promoting cell invasion. Alpha-3/beta-1 may mediate with LGALS3 the stimulation by CSPG4 of endothelial cells migration.

Product Specifications

Background

Specifications

Human ITGA3&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA3 and ITGB1, has a calculated MW of 133.3 kDa (ITGA3) and 83.7 kDa (ITGB1) . Subunit ITGA3 is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB1 contains no tag but a basic tail at the C-terminus. The non-reducing (NR) protein migrates as 125-150 kDa (ITGA3) and 100-110 kDa (ITGB1) respectively due to glycosylation.
