SLAMF1 (signaling lymphocytic activation molecule family member1), also known as SLAM and CD150, is a single-pass type I transmembrane 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. SLAMF1 contains 1 Ig-like V-type and 1 Ig-like C2-type domains in the extracellular region and 3 ITSM (immunoreceptor tyrosine switch motifs) in the cytoplasmic region. SLAMF1 is expressed on lymphocytes, thymocytes, macrophages, dendritic cells, platelets, and hematopoietic stem cells.  Its expression is up­regulated on lymphocytes cells after activation. As a self-ligand, SLAMF1 plays an important role in bidirectional T-cell to B-cell stimulation.  It performs diverse immunologic functions including T/B-cell costimulation, induction of interferon-γ in Th1 T-cell clones, redirection of Th2 clones to a Th1 or Th0 phenotype, and inhibition of apoptosis in B cells. SLAMF1 ligation also promotes an allergen­induced eosinophil and mast cell activation, NKT cell development, and the microbicidal response of macrophages. In human, SLAMF1 also functions as a cellular entry receptor for measles virus.

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.
