Description: The monoclonal antibody 162 recognizes CRACC (CD2 like receptor for activating cytotoxic cells) also known as CD319 and CS1. It is a member of the SLAM receptor family. CRACC is a 66kDa glycosylated transmembrane protein which contains a cytoplasmic ITSM domain (Immunoreceptor Tyrosine-based Switch Motif). It is this domain, found in other proteins such as CD244 and NTB-A, that interacts with SH2 containing proteins such as SAP. Interestingly the ITSM domain in CRACC is SAP independent. Instead EAT-2 acts as the signaling molecule for CRACC. This has profound impact for patients with X-linked lymphoproliferative disease (contains a SAP mutation). It should be noted that a splice variant has been reported which deletes the ITSM domain. Applications Reported: This 162 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 162 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (1 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.

SLAMF7 contains one Ig-like C2-type (immunoglobulin-like) domain. Isoform 1 mediates NK cell activation through a SAP-independent extracellular signal-regulated ERK-mediated pathway. It may play a role in lymphocyte adhesion. Isoform 3 does not mediate any activation. SAP can bind the cytoplasmic tail of isoform 1 when phosphorylated in the presence of Fyn (in vitro). SLAMF7 is expressed in spleen, lymph node, peripheral blood leukocytes, bone marrow, small intestine, stomach, appendix, lung and trachea. Expression was detected in NK cells, activated B-cells, NK-cell line but not in promyelocytic, B-, or T-cell lines. The isoform 3 is expressed at much lower level than isoform 1. There are three named isoforms.
