表达区间及表达系统(Source)

Human ITGAD&ITGB2 Heterodimer Protein, His Tag&Tag Free (IT2-H52W5) is expressed from human 293 cells (HEK293). It contains AA Phe 18 - Asn 1099 (ITGAD) & Gln 23 - Asn 700 (ITGB2) (Accession # Q13349-1(ITGAD) & P05107-1(ITGB2)).

蛋白结构(Molecular Characterization)

Online-Res(Phe 18 - Asn 1099 (ITGAD) & Gln 23 - Asn 700 (ITGB2)) Q13349-1 (ITGAD) & P05107-1 (ITGB2)

Human ITGAD & ITGB2 Heterodimer Protein, produced by co-expression of ITGAD and ITGB2, has a calculated MW of 125 kDa (ITGAD) & 80.1 kDa (ITGB2). Subunit ITGAD is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB2 contains no tag but a basic tail at the C-terminus.

背景(Background)

Integrin alpha-D/beta-2 is a receptor for ICAM3 and VCAM1. May play a role in the atherosclerotic process such as clearing lipoproteins from plaques and in phagocytosis of blood-borne pathogens, particulate matter, and senescent erythrocytes from the blood. Contributes to natural killer cell cytotoxicity. Involved in leukocyte adhesion and transmigration of leukocytes including T-cells and neutrophils. Triggers neutrophil transmigration during lung injury through PTK2B/PYK2-mediated activation (PubMed:18587400). Alpha D beta 2, selectively binds ICAM-3 and does not appear to bind ICAM-1. In addition, a soluble form of alpha D beta 2 binds VCAM-1 with greater efficiency relative to ICAM-3. The I domain of alpha D contains a binding site for VCAM-1 since recombinant alpha D I domain binds specifically to VCAM-1.
