Leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) is constitutively expressed on the majority of human peripheral blood mononuclear leukocytes.
LAIR-1 or CD305 is a transmembrane glycoprotein with a single immunoglobulin-like domain and a cytoplasmic tail containing two immune receptor tyrosine-based inhibitory motifs.
LAIR-1 recruits SHP-1 and SHP-2 phosphatases upon activation, and cross-linking of the LAIR-1 antigen on natural killer (NK) cells results in strong inhibition of NK cell–mediated cytotoxicity.
Functions as an inhibitory receptor that plays a constitutive negative regulatory role on cytolytic function of natural killer (NK) cells, B-cells and T-cells.
Activation by Tyr phosphorylation results in recruitment and activation of the phosphatases PTPN6 and PTPN11.
It also reduces the increase of intracellular calcium evoked by B-cell receptor ligation.Diseases associated with LAIR1 include Chronic Active Epstein-Barr Virus Infection and Palindromic Rheumatism.
特徴
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag).
The protein has a calculated MW of 19.2 kDa.
The protein migrates as 30-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
