      Background InformationT-lymphocyte surface antigen Ly-9 (UniProt: Q01965; also known as Cell surface molecule Ly-9, Lymphocyte antigen 9, SLAM family member 3, SLAMF3, Signaling lymphocytic activation molecule 3, CD229) is encoded by the Ly9 (also known as Ly-9) gene (Gene ID: 17085) in murine species. Ly-9 is a single-pass type I membrane protein that serves as a homophilic cell surface receptor present on all lymphocytes and is highly expressed on innate like lymphocytes. Its activity is controlled by presence or absence of small cytoplasmic adapter proteins, SH2D1A/SAP and/or SH2D1B/EAT-2. Ly-9 plays a negative role in the signaling pathways required for innate-like lymphocyte (iNKT) development in the thymus. It also promotes T-cell differentiation into a helper T-cell Th17 phenotype leading to increased IL-17 secretion. Ly-9 is synthesized with a signal peptide (aa 1-47) that is cleaved off in the mature form. The mature form has an extracellular domain (aa 48-453), a short transmembrane domain (aa 454-474), and a cytoplasmic domain (aa 475-654). The extracellular domain contains two Ig-like V type (aa 48-158 and 250-362) and two Ig-like C type (aa 159-243 and 353-453) domains. In addition, LY-9 has two immunoreceptor tyrosine-based switch motifs (ITSM) motifs (aa 599-604 and 623-628), which mediate the interaction with the SH2 domain of SH2D1A and SH2D1B. Ly-9 deficient mice are reported to develop normally, but exhibit a significant difference in the distribution of thymocyte subsets compared to wild types. This antibody (clone Ly9.7.144) is shown to reduce the number of iNKT cells in the spleen and also reduce the absolute number of both NKT1 and NKT2 cells. (Ref.: Sintes, J., et al. (2013). J.
