SLAMF5 (signaling lymphocytic activation molecule family member5), also known as Ly9B and CD84, 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. SLAMF5 contains 1 Ig-like V-type and 1 Ig-like C2-type domains in the extracellular region and 2 ITSM (immunoreceptor tyrosine switch motifs) in the cytoplasmic region. SLAMF5 exhibits extensive, cell type­specific glycosylation and homophilic binding that is mediated by its Ig­like V-type domain. The hemophilic interaction induces tyrosine phosphorylation in the cytoplasmic ITSMs, which in turn recruit the signaling adaptor molecules and activates downstream events. SLAMF5 is widely expressed among hematopoietic cells including hematopoietic stem cells, myeloid cells, platelets, megakaryocytes, and lymphocytes. SLAMF5 signaling modulates both adaptive and innate immune responses. It inhibits mast cell activation but enhances platelet activation, macrophage activation, T cell proliferation and IFN­γ production as well as the interactions between T cells and B cells for germinal center formation.

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.
