[[http://www.uniprot.org/uniprot/LAIR1_HUMAN LAIR1_HUMAN]] 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. May also play its inhibitory role independently of SH2-containing phosphatases. Modulates cytokine production in CD4+ T-cells, down-regulating IL2 and IFNG production while inducing secretion of transforming growth factor beta. Down-regulates also IgG and IgE production in B-cells as well as IL8, IL10 and TNF secretion. Inhibits proliferation and induces apoptosis in myeloid leukemia cell lines as well as prevents nuclear translocation of NF-kappa-B p65 subunit/RELA and phosphorylation of I-kappa-B alpha/CHUK in these cells. Inhibits the differentiation of peripheral blood precursors towards dendritic cells.<ref>PMID:9285412</ref> <ref>PMID:10229813</ref> <ref>PMID:10764762</ref> <ref>PMID:9692876</ref> <ref>PMID:11069054</ref> <ref>PMID:11160222</ref> <ref>PMID:12072189</ref> <ref>PMID:15939744</ref> <ref>PMID:15950745</ref> <ref>PMID:16380958</ref>
