分子別名(Synonym)
FCGR3
表達(dá)區(qū)間及表達(dá)系統(tǒng)(Source)
Mouse CD16, His Tag (CDA-M52H8) is expressed from human 293 cells (HEK293). It contains AA Leu 32 - Thr 215 (Accession # Q5D5I8).
Predicted N-terminus: Leu 32
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 23.0 kDa. The protein migrates as 36-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
CD16是一種低親和力Fc受體,已被鑒定為Fc受體FcγRIIIa(CD16a)和FcγRIII/b(CD16b)。這些受體與IgG抗體的Fc部分結(jié)合。CD16由兩個(gè)不同的高度同源基因以細(xì)胞類型特異的方式編碼。CD16存在于自然殺傷細(xì)胞、中性粒細(xì)胞、多形核白細(xì)胞、單核細(xì)胞和巨噬細(xì)胞的表面。
CD16a抗原也稱為低親和力免疫球蛋白γFc區(qū)受體III-A、FcγRIIIα。CD16b是一種低親和力的GPI連接受體,由中性粒細(xì)胞和嗜酸性粒細(xì)胞表達(dá),而CD16a是一種中等親和力的多肽錨定跨膜糖蛋白,由自然殺傷細(xì)胞、巨噬細(xì)胞、T細(xì)胞亞群、未成熟胸腺細(xì)胞和胎盤滋養(yǎng)層細(xì)胞表達(dá)。CD16a參與吞噬作用、酶和炎癥介質(zhì)的分泌、抗體依賴性細(xì)胞毒性和免疫復(fù)合物的清除。CD16a的異常表達(dá)或突變與復(fù)發(fā)性病毒感染、系統(tǒng)性紅斑狼瘡和同種免疫新生兒中性粒細(xì)胞減少癥的易感性有關(guān)。
