About This Kit
Human 2B4/CD244 quantitates human 2B4/CD244 in serum, plasma, supernatant. The assay will exclusively recognize both natural and recombinant human 2B4/CD244.
Target information
CD244 (2B4, SLAMF4) is a cell surface receptor expressed on natural killer (NK) cells (and some T cells) that mediate non-major histocompatibility complex (MHC) restricted killing. The interaction between NK-cell and target cells via CD244 is thought to modulate NK-cell cytolytic activity. CD244 interacts with SLAMF2, causing the activation of both SLAMF4- and SLAMF2-expressing cells. Patients with systemic lupus erythmatosus have lower than normal levels of SLAMF4 expressed on their NK cells and monocytes, suggesting that SLAMF4 may play a role in the pathology of this autoimmune disease. Diseases associated with CD244 dysfunction include rheumatoid arthritis and lymphoproliferative syndrome. Alternatively spliced transcript variants encoding different isoforms of CD244 have been found for this gene.
