Summaries for LY9 Gene

Entrez Gene Summary for LY9 Gene

  • LY9 belongs to the SLAM family of immunomodulatory receptors (see SLAMF1; MIM 603492) and interacts with the adaptor molecule SAP (SH2D1A; MIM 300490) (Graham et al., 2006 [PubMed 16365421]).[supplied by OMIM, Mar 2008]

GeneCards Summary for LY9 Gene

LY9 (Lymphocyte Antigen 9) is a Protein Coding gene. Diseases associated with LY9 include Systemic Lupus Erythematosus. Among its related pathways are Hematopoietic Stem Cell Differentiation Pathways and Lineage-specific Markers. GO annotations related to this gene include receptor activity. An important paralog of this gene is CD84.

UniProtKB/Swiss-Prot for LY9 Gene

  • Self-ligand receptor of the signaling lymphocytic activation molecule (SLAM) family. SLAM receptors triggered by homo- or heterotypic cell-cell interactions are modulating the activation and differentiation of a wide variety of immune cells and thus are involved in the regulation and interconnection of both innate and adaptive immune response. Activities are controlled by presence or absence of small cytoplasmic adapter proteins, SH2D1A/SAP and/or SH2D1B/EAT-2. May participate in adhesion reactions between T lymphocytes and accessory cells by homophilic interaction. Promotes T-cell differentiation into a helper T-cell Th17 phenotype leading to increased IL-17 secretion; the costimulatory activity requires SH2D1A (PubMed:22184727). Promotes recruitment of RORC to the IL-17 promoter (PubMed:22989874). May be involved in the maintenance of peripheral cell tolerance by serving as a negative regulator of the immune response. May disable autoantibody responses and inhibit IFN-gamma secretion by CD4(+) T-cells. May negatively regulate the size of thymic innate CD8(+) T-cells and the development of invariant natural killer T (iNKT) cells (By similarity).

LY9_HUMAN :
  • The ITSMs (immunoreceptor tyrosine-based switch motifs) with the consensus sequence T-X-Y-X-X-[VI] present in SLAM family receptors have overlapping specificity for activating and inhibitory SH2 domain-containing binding partners. Especially they mediate the interaction with the SH2 domain of SH2D1A and SH2D1B. A three-pronged mechanism is proposed involving threonine (position -2), phosphorylated tyrosine (position 0) and valine/isoleucine (position +3).
