分子別名(Synonym)
Integrin alpha 2 beta 1,ITGA2 & ITGB1
表達(dá)區(qū)間及表達(dá)系統(tǒng)(Source)
Human ITGA2&ITGB1 Heterodimer Protein, His Tag&Tag Free (IT1-H52W6) is expressed from human 293 cells (HEK293). It contains AA Tyr 30 - Thr 1132 (ITGA2) & Gln 21 - Asp 728 (ITGB1) (Accession # P17301-1 (ITGA2) & P05556-1 (ITGB1)).
Predicted N-terminus: Tyr 30 (ITGA2) & Gln 21 (ITGB1)
蛋白結(jié)構(gòu)(Molecular Characterization)
Human ITGA2&ITGB1 Heterodimer Protein, His Tag&Tag Free, produced by co-expression of ITGA2 and ITGB1, has a calculated MW of 127.6 kDa (ITGA2) and 83.7 kDa (ITGB1). Subunit ITGA2 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 reducing (R) protein migrates as 150-160 kDa (ITGA2) and 105-135 kDa (ITGB1) respectively due to glycosylation.
