分子别名(Synonym)
CD79b,B29,IGB,Ig-beta
表达区间及表达系统(Source)
Human CD79B, His Tag (CDB-H52H3) is expressed from human 293 cells (HEK293). It contains AA Ala 29 - Asp 159 (Accession # P40259-1).
Predicted N-terminus: Ala 29
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 17.1 kDa. The protein migrates as 30-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, 0.2 M Arginine, pH7.4 with trehalose as protectant.

背景(Background)
B细胞抗原受体复合物相关蛋白β链(CD79b)也称为B细胞特异性糖蛋白B29、Igβ、免疫球蛋白相关B29蛋白、B29和IGB,它是一种单程I型膜蛋白,含有一个Ig样V型(免疫球蛋白样)结构域和一个ITAM结构域。CD79b需要与CD79A协同作用,以启动由B细胞抗原受体复合物(BCR)激活的信号转导级联。CD79b可能通过招募磷酸化CD79A的激酶或招募与CD79A结合并保护其免受去磷酸化的蛋白质来增强CD79A磷酸化。CD79b的缺陷是6型无丙种球蛋白血症(AGM6)的原因,AGM6是一种原发性免疫缺陷,其特征是由于B细胞发育的早期阻断,血清抗体极低或缺失,循环B细胞低或缺失。
