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

  • Synonym
    Integrin alpha 3 beta 1,ITGA3&ITGB1
  • Source
    Rat ITGA3 & ITGB1 Heterodimer Protein, His Tag&Tag Free(IT1-R53Wb) is expressed from CHO cells. It contains AA Phe 33 - Glu 992 & Gln 21 - Asp 729 (Accession # I4DUB5 & P49134).
    Predicted N-terminus: Phe 33 & Gln 21
  • Molecular Characterization
    Integrin alpha 3 beta 1 Structure

    Rat ITGA3 & ITGB1 Heterodimer Protein, His Tag&Tag Free, has a calculated MW of 113.4 kDa (ITGA3) & 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.

  • Endotoxin

  • Background
    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.
