Anti-IL17B antibodies are used in the immunodetection of the protein interleukin 17B. In humans, the canonical protein has a reported length of 180 amino acid residues and a mass of 20.4 kDa. It is known to be a secreted protein. It is reported to be expressed in adult pancreas, small intestine, stomach, spinal cord and testis. A member of the IL-17 protein family, it is known to be involved with cell to cell signaling and immune response pathways. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include NIRF, ZCYTO7, cytokine-like protein ZCYTO7, interleukin-17 beta, neuronal interleukin-17 related factor, and IL-20.
