Avoid repeated freeze-thaws. |
| Target description: | T-cell surface glycoprotein CD5 (UniProt: P06127; also known as Lymphocyte antigen T1/Leu-1, CD5) is encoded by the CD5 (also known as LEU1) gene (Gene ID: 921) in human. CD5 is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-24), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 25-372), a transmembrane domain (aa 373-402), and a cytoplasmic domain (aa 403-495). The extracellular region contains three scavenger receptor cysteine rich (SRCR) domains. CD5 is expressed on the surface of all T cells bearing the β heterodimer T cell receptor (TCR) but is absent or present at lower density on the T cell subset. It is involved in the regulation of T cell function and proliferation. It is also detected on a subset of B cells, specifically the B1 cells. However, B cells usually express two-to-five-fold fewer CD5 molecules per cell than T cells. In B cells, CD5 promotes constitutive activation of pERK1/2 in a calcium-dependent manner and involves the non-selective TRPC1 channel. In the C-terminal region, CD5 contains four tyrosine residues that can be phosphorylated by Lyn kinase to create binding sies for SHP-1 (PTPN6). CD5 is shown to be constitutively associated with SHP-1 and their interaction increases upon TCR stimulation. In mature, peripheral T cells, CD5 is present in lipid rafts of the T cell surface, where it promotes CD3 redistribution into rafts, which upregulates the activation of ZAP-70, linker for activation of T cells (LAT), and Ca2+ influx. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
