b淋巴细胞抗原受体是一种多聚体复合物，包括抗原特异性成分表面免疫球蛋白（ig）。表面ig与另外两种蛋白igα和igβ非共价结合，这是b细胞抗原受体表达和功能所必需的。该基因编码b细胞抗原成分的igα蛋白。另外，还描述了编码不同亚型的剪接转录变体。[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]
