Human LY9 Recombinant Protein (RPPB3894)

Lymphocyte Antigen 9, also known as LY9 is a member of the SLAM familyof immunomodulatory receptors, LY9 interacts with the adaptor molecule SAP . LY9 plays a part in adhesion reactions between T lymphocytes andaccessory cells via homophilic interaction. LY9 promotes T-cell differentiationinto a helper T-cell Th17 phenotype which leads to increased IL-17 secretion;the costimulatory activity requires SH2D1A. Furthermore it also promotesrecruitment of RORC to the IL-17 promoter. LY9 is implicated in the maintenanceof peripheral cell tolerance through serving as a negative regulator of theimmune response. LY9 disables autoantibody responses as well as inhibitsIFN-gamma secretion by CD4(+) T-cells. Moreover, LY9 negatively regulate thesize of thymic innate CD8(+) T-cells and the development of invariant naturalkiller T (iNKT) cells. Systemic Lupus Erythematosus is one of the diseases whichare associated with LY9.�

LY9 Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 416 amino acids (48-454 aa) and having a molecular mass of 45.9kDa (Migrates at 40-57kDa on SDS-PAGE under reducing conditions).LY9 is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
