Source

Biotinylated Cynomolgus ITGA4&ITGB7 Heterodimer Protein, His,Avitag&Tag Free (IT7-C82W3) is expressed from human 293 cells (HEK293). It contains AA Tyr 34 - Gln 970 (ITGA4) & Glu 20 - His 723 (ITGB7) (Accession # XP_005573683.2 (ITGA4) & XP_005571028.2 (ITGB7)).

Predicted N-terminus: Tyr 34 (ITGA4) & Glu 20 (ITGB7)

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

Biotinylated Cynomolgus ITGA4&ITGB7 Heterodimer Protein, His,Avitag&Tag Free, produced by co-expression of ITGA4 and ITGB7, has a calculated MW of 112.9 kDa (ITGA4) & 81.6 kDa (ITGB7). Subunit ITGA4 is fused with an acidic tail at the N-terminus and followed by a polyhistidine tag and an Avi tag (Avitag™) and subunit ITGB7 contains no tag but a basic tail at the N-terminus. The protein migrates as 150-160 kDa and 100-120 kDa, 65-80 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a heterodimer.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

Protein Ratio

Passed as determined by the SABA assay / HABA assay / binding ELISA.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background

Integrin alpha 4 beta 7 is an integrin family adhesion receptor that shares subunits with alpha 4 beta 1 (VLA4) and the E-Cadherin receptor, alpha E beta 7 . Integrin alpha 4 beta 7, which is critical for homing to intestinal mucosa, is induced during T cell activation in Peyer’s patches or mesenteric lymph nodes.Its expression requires signals from local dendritic and stromal cells, including secreted retinoic acid. The HIV-1 envelope protein gp120 binds to the active form of Integrin alpha 4 beta 7, and this may or may not account for the concentration of HIV-1 virus in the gut-associated lymphoid tissue (GALT). Integrin alpha 4 beta 7 may also be involved in lymphocyte trafficking in acute intestinal graft vs. host disease (GVHD).
