分子别名（Synonym）
Integrin alpha 5 beta 1,ITGA5&ITGB1
表达区间及表达系统（Source）
Human ITGA5&ITGB1 Heterodimer Protein, His Tag&Tag Free (IT1-H52W5) is expressed from human 293 cells (HEK293). It contains AA Phe 42 - Tyr 995 (ITGA5) & Gln 21 - Asp 728 (ITGB1) (Accession # P08648-1 (ITGA5) & P05556-1 (ITGB1)).
Predicted N-terminus: Phe 42 (ITGA5) & Gln 21 (ITGB1)
蛋白结构（Molecular Characterization）
Human ITGA5&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA5 and ITGB1, has a calculated MW of 110.7 kDa (ITGA5) and 83.7 kDa (ITGB1). Subunit ITGA5 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 130-150 kDa (ITGA5) and 100-120 kDa (ITGB1) when calibrated against Star Ribbon Pre-stained Protein Marker respectively due to glycosylation.
内毒素（Endotoxin）

背景（Background）
整合素α5β1/Integrinα5β1是细胞外基质蛋白纤维连接蛋白的主要细胞受体，在哺乳动物发育过程中起着重要作用。由α5（ITGA5/CD49e）和β1（ITGB1/CD29）亚基组成。整合素是粘附受体，通过质膜传递双向信号。整合素α5β1及其主要细胞外基质配体纤维连接蛋白（Fn）具有重要的生物学意义。
