Cynomolgus Siglec-3 / CD33 Protein, His Tag
分子别名(Synonym)
CD33,SIGLEC3,gp67
表达区间及表达系统(Source)
Cynomolgus Siglec-3, His Tag (CD3-C52H4) is expressed from human 293 cells (HEK293). It contains AA Met 16 - Leu 228 (Accession # XP_045235686.1).
Predicted N-terminus: Met 16
蛋白结构(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 25.7 kDa. The protein migrates as 38-43 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.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
骨髓细胞表面抗原CD33也被称为SIGLEC3、Siglecs(唾液酸结合Ig样凝集素)和GP67,是一种单通道I型膜蛋白,属于免疫球蛋白超家族和SIGLEC(唾液酸连接Ig类凝集素)家族。人CD33/Siglec-3 cD编码一个364个氨基酸(aa)的多肽,具有疏水信号肽、N端Ig样V型结构域、一个Ig样C2型结构域,一个跨膜区和一个细胞质尾部。CD33/Siglec-3通常被认为是髓系特异性的,但也可以在一些淋巴细胞上发现。在免疫反应中,CD33/Siglec-3可能通过其SH2结构域招募细胞质磷酸酶,阻断信号分子去磷酸化的信号转导,从而对配体诱导的酪氨酸磷酸化起到抑制受体的作用。CD33/Siglec-3诱导急性髓系白血病细胞凋亡。
