  • Immunohistochemical analysis of paraffin-embedded human Tonsil tissue using CD33 antibody was performed. The section was pretreated using high-temperature and high-pressure mediated EDTA antigen retrieval buffer (pH 9.0), for 5 minutes. The tissues were incubated with primary antibody (HY-P81563, 1:1000 dilution) at room temperature for 60 minutes. Detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. The tissues were counterstained with hematoxylin and mounted with neutral balsam mounting medium.

背景
功能:唾液酸结合免疫球蛋白样凝集素 (Siglec) 在介导细胞间相互作用和维持免疫细胞静息状态中发挥作用 (PubMed:10611343, PubMed:11320212, PubMed:15597323)。它优先识别并结合 α-2,3 连接的唾液酸糖链,对 α-2,6 连接的唾液酸糖链的亲和力更高 (PubMed:7718872)。当与 C1q 或唾液酸化糖蛋白等配体结合时,位于 CD33 胞质尾部的两个免疫受体酪氨酸抑制基序 (ITIM) 会被 Src 样激酶 (例如 LCK) 磷酸化 (PubMed:10887109, PubMed:28325905)。这些磷酸化位点为蛋白酪氨酸磷酸酶 PTPN6/SHP-1 和 PTPN11/SHP-2 的募集和激活提供了对接位点 (PubMed:10206955, PubMed:10556798, PubMed:10887109)。反过来,这些磷酸酶通过信号分子的去磷酸化来调节下游通路 (PubMed:10206955, PubMed:10887109)。CD33 对单核细胞活化的抑制作用之一需要磷脂酰肌醇 3-激酶/PI3K (PubMed:15597323)。
亚细胞定位:细胞膜;单次跨膜 I 型膜蛋白;过氧化物酶体
表达水平:
组织特异性:单核细胞/髓系细胞。在脑内,CD33 主要表达于小胶质细胞。
异构体 & 翻译后修饰:P20138 有 3 种异构体:P20138-1:39825 Da (预测值);P20138-2:33890 Da (预测值);P20138-3:25293 Da (预测值)。
糖基化修饰。Asn-100 的糖基化对于配体识别的调控至关重要;Tyr-340 的磷酸化参与与 PTPN6 和 PTPN11 的结合。Tyr-358 的磷酸化参与与 PTPN6 的结合。LCK 能有效磷酸化 Tyr-340,对 Tyr-358 的磷酸化作用较弱。
亚基:同源二聚体;二硫键连接 (PubMed:10887109)。磷酸化后与 PTPN6/SHP-1 和 PTPN11/SHP-2 相互作用 (PubMed:10206955,PubMed:10556798)。

  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
