SLAMF2 (signaling lymphocytic activation molecule family member2), also known as BLAST­1 and CD48, is a GPI­anchored glycoprotein that belongs to the SLAM subfamily of the CD2 protein family of the Ig (immunoglobulin) superfamily. Most SLAM family members function as adhesion molecules and co-receptors for lymphocyte activation and mediate tyrosine phosphorylation signals. SLAMF2 contains 1 Ig-like V-type and 1 Ig-like C2-type domains in the extracellular region. SLAMF2 is expressed on most lineage­committed hematopoietic cells but not on hematopoietic stem cells or progenitors. CD48 plays important roles in a variety biological processes including adhesion, pathogen recognition, cellular activation, and cytokine regulation, and emerges as a critical effector molecule in immune responses. CD2, SLAMF4 (also known as 2B4 and CD244), and heparan sulfate function as CD48 ligands. In mice, CD48­CD2 interactions promote T cell activation and class switching to IgG2a in B cells.  In human, high affinity CD48­CD244 interactions can either promote or inhibit NK cell and cytotoxic T cell (CTL) activation. A soluble form of CD48 is detected in the serum of lymphoid leukemia and arthritis patients.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CGGGAAGCAATAGCATGATA-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
