表達區(qū)間及表達系統(tǒng)（Source）
Human ITGAV&ITGB5 Heterodimer Protein, His Tag&Tag Free (IT5-H52W5) is expressed from human 293 cells (HEK293). It contains AA Phe 31 - Val 992 (ITGAV) & Gly 24 - Asn 719 (ITGB5) (Accession # NP_002201.1 (ITGAV) & NP_002204.2 (ITGB5)).
Predicted N-terminus: Phe 31 (ITGAV) & Gly 24 (ITGB5)
蛋白結構（Molecular Characterization）
Human ITGAV&ITGB5 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGAV and ITGB5, has a calculated MW of 112.9 kDa (ITGAV) and 81.9 kDa (ITGB5). Subunit ITGAV is fused with polyhistidine tag at the C-terminus and followed by a acidic tail and subunit ITGB5 contains no tag but a basic tail at the C-terminus. The non-reducing (NR) protein migrates as 130-150 kDa (ITGAV) and 85-95 kDa (ITGB5) respectively due to glycosylation.
內毒素（Endotoxin）

背景（Background）
整合素αVβ5（ITGAV和ITGB5）在多種細胞類型上表達，包括角質形成細胞、成纖維細胞、粘附性單核細胞、胚胎干細胞以及特定的內皮和上皮細胞。ITGAV和ITGB5結合含有RGD基序的配體，特別是玻連蛋白。增加PKC活性的生長因子，如VEGF或TGF-α，促進ITGAV和ITGB5介導的血管生成，而可能在同一細胞中表達的αVβ3對FGF堿性和TNF-α有反應。兩者的抑制劑都能下調腫瘤血管生成。在肺部炎癥期間，肌成纖維細胞或浸潤淋巴細胞上ITGAV和ITGB5的上調可能通過釋放TGF-β來促進纖維化。
