Summaries for LTB Gene

Entrez Gene Summary for LTB Gene

  • Lymphotoxin beta is a type II membrane protein of the TNF family. It anchors lymphotoxin-alpha to the cell surface through heterotrimer formation. The predominant form on the lymphocyte surface is the lymphotoxin-alpha 1/beta 2 complex (e.g. 1 molecule alpha/2 molecules beta) and this complex is the primary ligand for the lymphotoxin-beta receptor. The minor complex is lymphotoxin-alpha 2/beta 1. LTB is an inducer of the inflammatory response system and involved in normal development of lymphoid tissue. Lymphotoxin-beta isoform b is unable to complex with lymphotoxin-alpha suggesting a function for lymphotoxin-beta which is independent of lympyhotoxin-alpha. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

GeneCards Summary for LTB Gene

LTB (Lymphotoxin Beta) is a Protein Coding gene. Among its related pathways are Cytokine Signaling in Immune system and Innate Immune System. Gene Ontology (GO) annotations related to this gene include receptor binding and tumor necrosis factor receptor binding.

UniProtKB/Swiss-Prot for LTB Gene

  • Cytokine that binds to LTBR/TNFRSF3. May play a specific role in immune response regulation. Provides the membrane anchor for the attachment of the heterotrimeric complex to the cell surface. Isoform 2 is probably non-functional.
