Lymphotoxin beta

Lymphotoxin-beta (LT-beta) also known as tumor necrosis factor C (TNF-C) is a is_associated_with::protein that in humans is encoded by the LTB is_associated_with::gene.

Function
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 is_associated_with::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.

Interactions
LTB has been shown to interact with is_associated_with::Lymphotoxin alpha.
