表達區(qū)間及表達系統(tǒng)（Source）
Human ITGAV&ITGB1 Heterodimer Protein, His Tag&Tag Free (IT1-H52E1) is expressed from human 293 cells (HEK293). It contains AA Phe 31 - Val 992 (ITGAV) & Gln 21 - Asp 728 (ITGB1) (Accession # NP_002201.1 (ITGAV) & NP_002202.2 (ITGB1)).
Predicted N-terminus: Phe 31 (ITGAV) & Gln 21 (ITGB1)
蛋白結(jié)構(gòu)（Molecular Characterization）
Human ITGAV&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGAV and ITGB1, has a calculated MW of 112.9 kDa (ITGAV) and 83.7 kDa (ITGB1). Subunit ITGAV 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 (ITGAV) and 95-110 kDa (ITGB1) respectively due to glycosylation.
內(nèi)毒素（Endotoxin）

背景（Background）
整合素α-5/β-1是纖維蛋白原的受體。整合素α-1/β-1、α-2/β-1，α-6/β-1和α-7/β-1是lamimin的受體。整合素α-4/β-1是VCAM-1的受體。它識別VCAM-1中的序列Q-I-D-S。整合素α-9/β-1是VCAM-1、細胞觸覺素和骨橋蛋白的受體。它識別細胞觸覺素中的序列A-E-I-D-G-I-E-L。整合素α-V/β-1也是玻連蛋白的受體。Beta-1整合素在多種配體中識別R-G-D序列。異構(gòu)體2干擾異構(gòu)體1，對細胞粘附和遷移（體外）產(chǎn)生顯性負面影響。當與α-7/β-1整合素結(jié)合時，調(diào)節(jié)細胞粘附和層粘連蛋白基質(zhì)沉積。
