目标描述

Forkhead box protein P3 (UniProt: Q9BZS1; also known as Scurfin, FoxP3) I encoded by the FOXP3 (also known as IPEX, JM2) gene (Gene ID: 50943) in human. FoxP3 is homodimeric protein that Is predominantly expressed in the cytoplasm in activated conventional T-cells whereas it is mainly expressed in the nucleus in regulatory T-cells (Treg). It serves as a transcriptional regulator and is crucial for the development and inhibitory function of regulatory T-cells. The 41 kDa form derived by proteolytic processing is found exclusively in the chromatin fraction of activated Treg cells. Its levels are reported to be down-regulated in regulatory T-cells during inflammation. FoxP3 can undergo proteolytic cleavage in activated regulatory T-cells and can be cleaved at either the N- (aa 51-52) or C-terminal (aa 417-418) site, or at both sites. FoxP3 plays an essential role in maintaining homeostasis of the immune system by allowing the acquisition of full suppressive function and stability of the Treg lineage, and by directly modulating the expansion and function of conventional T-cells. Its dimerization is reported to be essential for its transcriptional regulator activity. Is phosphorylation at serine 418 is shown to regulate its transcriptional repressor activity and consequently, regulatory T-cells suppressive function. FoxP3 is synthesized with a propeptide (aa 418-431), which is subsequently cleaved off in the mature form. Its nuclear localization signal is in the amino acids 414-417 and 68-76 and its nuclear export signal is localized in amino acids 239-249. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
