LILRA3
Function
Acts as a soluble receptor for class I MHC antigens. Binds both classical and non-classical HLA class I molecules but with reduced affinities compared to LILRB1 or LILRB2. Binds with high affinity to the surface of monocytes, leading to abolish LPS-induced TNF-alpha production by monocytes.
Post-translational modifications
N-glycosylation is required for ligand binding.
Tissue Specificity
Detected in B-cells, and at lower levels in natural killer (NK) cells. Detected in peripheral blood monocytes and lung.
Cellular localization
- Secreted
