b淋巴細胞抗原受體是一種多聚體復合物，包括抗原特異性成分表面免疫球蛋白（ig）。表面ig與另外兩種蛋白igα和igβ非共價結合，這是b細胞抗原受體表達和功能所必需的。該基因編碼b細胞抗原成分的igα蛋白。另外，還描述了編碼不同亞型的剪接轉錄變體。[由RefSeq提供，2008年7月]
The B lymphocyte antigen receptor is a multimeric complex that includes the antigen-specific component, surface immunoglobulin (Ig). Surface Ig non-covalently associates with two other proteins, Ig-alpha and Ig-beta, which are necessary for expression and function of the B-cell antigen receptor. This gene encodes the Ig-alpha protein of the B-cell antigen component. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
