CD45antigen (Protein tyrosine phosphatase, receptor type, C also known as PTPRC and formerly known as leukocyte common antigen LCA)
Protein tyrosine phosphatase, receptor type, C also known as PTPRC is an enzyme that, in humans, is encoded by the PTPRCgene.[5] PTPRC is also known as CD45antigen (CD stands for cluster of differentiation), which was originally called leukocyte common antigen (LCA).[6] Function The protein product of this gene, best known as CD45, is a member of the protein tyrosine phosphatase (PTP) family. PTPs are signaling molecules that regulate a…

CD4
In molecular biology, CD4 (cluster of differentiation 4) is a glycoprotein that serves as a co-receptor for the T-cell receptor (TCR). CD4 is found on the surface of immune cells such as T helper cells, monocytes, macrophages, and dendritic cells. It was discovered in the late 1970s and was originally known as leu-3 and T4 (after the OKT4 monoclonal antibody that reacted with it) before being named CD4 in 1984.[5] In humans,…
