MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygotes for targeted null mutations lack peripheral lymph nodes, Peyer's patches, splenic germinal centers and follicular dendritic cells. Mutants exhibit lymphocytosis in the circulation and peritoneal cavity with infiltrations of the lung and liver. [provided by MGI curators]
