分子别名(Synonym)
FCGR3A,CD16A,FCG3,FCGR3,IGFR3
表达区间及表达系统(Source)
Human CD16a (F176), His Tag (CDA-H5220) is expressed from human 293 cells (HEK293). It contains AA Gly 17 - Gln 208 (Accession # P08637-1).
Predicted N-terminus: Gly 17
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 23.7 kDa. The protein migrates as 39-51 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度(Purity)
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
CD16是低亲和力Fc受体,包含FcγRIIIa(CD16a)和FcγRIIIb(CD16b)两种亚型。该受体可与IgG抗体的Fc段结合,由两个高度同源基因以细胞类型特异性方式编码,表达于自然杀伤细胞、中性粒细胞、单核细胞及巨噬细胞表面。
CD16a亦称低亲和力免疫球蛋白γ Fc区受体III-A(Fcγ RIII-α),而CD16b是中性粒细胞和嗜酸性粒细胞表达的GPI锚定低亲和力受体;CD16a则为跨膜糖蛋白(多肽锚定型),具中等亲和力,分布于自然杀伤细胞、巨噬细胞、T细胞亚群、未成熟胸腺细胞及胎盘滋养层细胞。CD16a参与介导吞噬作用、促进酶及炎性介质分泌、执行抗体依赖的细胞毒性反应(ADCC)并清除免疫复合物。其异常表达或突变与复发性病毒感染易感性、系统性红斑狼疮及同种免疫性新生儿中性粒细胞减少症相关。
