Integrin alpha V beta 6, ITGAV&ITGB6
Human Integrin alpha V beta 6 (ITGAV&ITGB6) Heterodimer Protein (Human ITGAV & ITGB6 Heterodimer Protein) Phe 31 - Val 992 (ITGAV) & Gly 22 - Asn 707 (ITGB6) (Accession # NP_002201 (ITGAV)& AAI21179 (ITGB6)) was produced in human 293 cells (HEK293) at ACROBiosystems.
Human ITGAV & ITGB6 Heterodimer Protein, produced by co-expression of ITGAV and ITGB6, has a calculated MW of 113 kDa (ITGAV) and 79.6 kDa (ITGB6). Subunit ITGAV is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB6 contains no tag but a basic tail at the C-terminus. The predicted N-terminus is Phe 31 (ITGAV) & Gly 22 (ITGB6). The reducing (R) protein migrates as 145 kDa (ITGAV) and 115 kDa (ITGB6) respectively due to glycosylation.
Less than 1.0 EU per μg of the Human ITGAV & ITGB6 Heterodimer Protein by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in Tris, NaCl and CaCl2. Normally Mannitol or Trehalose are added as protectants before lyophilization.

Immobilized Human ITGAVB6, His Tag (Catalog # IT6-H52E1) at 2μg/mL (100 μL/well) can bind Human TGF-Beta 1 / TGFB1, His Tag & Avi Tag with a linear range of 2-39 ng/mL.
Integrin alpha V beta 6 is a heterodimer of beta-6 associating with alpha-V. Integrin alpha-V beta-6 is a receptor for fibronectin and cytotactin. It recognizes the sequence R-G-D in its ligands. Internalisation of integrin alpha-V beta-6 via clathrin-mediated endocytosis promotes carcinoma cell invasion. Also, Integrin alpha-V beta-6 acts as a receptor for coxsackievirus A9 and coxsackievirus B1 as well as herpes simplex virus-1/HHV-1. Furthermore, it binds the TGF-beta latency‑associated peptide (LAP) and activates TGF-beta 1 or TGF-beta 3 from large latent complexes. This activation requires interaction with LTBP-1 and fibronectin, and is enhanced by PAR-1.
