2B4/CD244/SLAMF4 Antibody Summary

Immunogen
Antibody was raised against a 16 amino acid synthetic peptide near the carboxy terminus of human SLAMF4. The immunogen is located within the last 50 amino acids of SLAMF4.
Specificity
At least three isoforms of SLAMF4 are known to exist. SLAMF4 antibody is predicted to not cross-react with other SLAM protein family members.

Background

The signaling lymphocyte-activation molecule family member 4 (SLAMF4), also known as 2B4, is an important regulator of Natural Killer (NK) cell activation. It is expressed on NK cells as well as on subsets of T cells and 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 this autoimmune disease.
