产品介绍 The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus belongs to receptor type PTP. This gene is specifically expressed in hematopoietic cells. This PTP has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes, or by activating various Src family kinases required for the antigen receptor signaling. This PTP also suppresses JAK kinases, and thus functions as a regulator of cytokine receptor signaling. Four alternatively spliced transcripts variants of this gene, which encode distinct isoforms, have been reported. [provided by RefSeq, Jul 2008].
CD45在活化信号转导中起到调节作用 在确定CD45为一种PTPase之前就已证实了CD45参于细胞的活化和生长调节。
抗CD45抗体可以抑制PHA或CD3交联所介导的T细胞增殖,还可抑制NK或细胞毒性T细胞对靶细胞的杀伤,抑制经CD2、CD3以及CD8膜分子介导的信号转导作用。
白细胞共同抗原是五种或更多的高分子量糖蛋白组成的蛋白家族,主要位于白细胞表面,包括T、B淋巴细胞、多形核白细胞、单核细胞等,而在红细胞、血小板及非造血系统中不表达。因此是区分淋巴瘤/白血病和非造血组织肿瘤(如未分化小细胞癌、小圆细胞肉瘤)的特异性标记物。该抗体主要用于淋巴瘤和未分化小细胞癌的鉴别诊断。
