LILRB5 (Leukocyte immunoglobulin like receptor B5), also known as CD85c, and LIR8 (Leukocyte immunoglobulin-like receptor 8),  is a member of the leukocyte immunoglobulin (Ig)-like receptor (LIR) family of the Ig superfamily (IgSF).  It belongs to the subfamily B class of LIR receptors (LILRBs), which are single-pass type I trnasmembrane proteins with 2 or 4 extracellular Ig-like domains, a transmembrane domain (TM), and 2-4 cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs). LILRB5 has 4 Ig-like C2 type domains and 2 TIIMs. The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases to modulate cellular responses.  LILRB5 is expressed predominantly on NK cells.  Like LILRB1 & LILRB, LILRB5 binds to MHC class I molecules on antigen-presenting cells (APCs) and transduces a negative signal that inhibits stimulation of an immune response. LILRB3 may control inflammatory responses and cytotoxicity to help focus the immune response and limit autoreactivity.

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’-CCAGGTTTCCGGGCCCTCAC-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.
