表達區(qū)間及表達系統(tǒng)（Source）
Human CD79A&CD79B Heterodimer Protein, Mouse IgG2a Fc,Flag Tag&Mouse IgG2a Fc,His Tag (CDB-H52W3) is expressed from human 293 cells (HEK293). It contains AA Leu 33 - Arg 143 (CD79A) & Ala 29 - Asp 159 (CD79B) (Accession # P11912-1 (CD79A) & P40259-1 (CD79B)).
Predicted N-terminus: Leu 33 (CD79A) & Ala 29 (CD79B)
蛋白結構（Molecular Characterization）
Human CD79A&CD79B Heterodimer Protein, Mouse IgG2a Fc,Flag Tag&Mouse IgG2a Fc,His Tag is produced by co-expression of CD79A and CD79B, has a calculated MW of 43.8 kDa (CD79A) and 46.7 kDa (CD79B). Subunit CD79A carries a mouse IgG2a Fc fragment at the C-terminus, followed by a flag tag and subunit CD79B carries a mouse IgG2a Fc fragment at the C-terminus, followed by a polyhistidine tag. The protein migrates as 120 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

背景（Background）
CD79a和CD79b異二聚體是B細胞受體（BCR）復合物的重要信號成分，在B細胞發(fā)育和抗體產(chǎn)生中起著至關重要的作用。BCR復合物由與信號成分非共價結合的配體結合受體（膜免疫球蛋白；mIg）、CD79a（Igα）和CD79b（Igβ）的二硫鍵連接異二聚體組成。這兩種CD79亞基都由一個Ig樣結構域、一個跨膜（TM）區(qū)域和一個較長的細胞質尾部（CYT）組成，該尾部包含一個基于免疫受體酪氨酸的激活基序（ITAM）。
