Tissue specificity:In general, low constitutive expression, if any, in healthy tissues; high expression in inflammatory counterparts, including in synovial tissues from individuals with active rheumatoid arthritis. Isoform A, isoform B and isoform C are expressed in testis, colon, placenta, lung and lymph node. Isoform D and isoform E were found only in testis and bone marrow. Whereas only isoform A is found in brain, only isoform B in kidney and only isoform C in heart. {ECO:0000269|PubMed:11145836, ECO:0000269|PubMed:20935647}.

Induction:Highly induced by bacterial lipopolysaccharides (LPS) and TGFB1, more moderately by IFNG, IL18, IL1B, TNF and the dinucleotide CpG (at protein level). Constitutive expression in bone marrow macrophages is down-regulated in the presence of IL4 and CSF2. Induced by phorbol myristate acetate (PMA) in different cell lines. {ECO:0000269|PubMed:18390730, ECO:0000269|PubMed:20935647}.

Developmental stage:
