Protein Information
Synonyms SIRPB2
Function Probable immunoglobulin-like cell surface receptor. On binding with CD47, mediates cell-cell adhesion. Engagement on T- cells by CD47 on antigen-presenting cells results in enhanced antigen-specific T-cell proliferation and costimulates T-cell activation.
Cellular Location Membrane; Single-pass type I membrane protein
Tissue Location Detected in liver, and at very low levels in brain, heart, lung, pancreas, kidney, placenta and skeletal muscle. Expressed on CD4+ T-cells, CD8+ T-cells, CD56-bright natural killer (NK) cells, CD20+ cells, and all activated NK cells. Mainly present in the paracortical T-cell area of lymph nodes, with only sparse positive cells in the mantle and in the germinal center of B-cell follicles. In the thymus, primarily expressed in the medulla on mature T-lymphocytes that have undergone thymic selection.

The protein encoded by this gene is a member of thesignal-regulatory protein (SIRP) family, and also belongs to theimmunoglobulin superfamily. SIRP family members are receptor-typetransmembrane glycoproteins known to be involved in the negativeregulation of receptor tyrosine kinase-coupled signaling processes.Alternatively spliced transcript variants encoding differentisoforms have been described.
