Summary: Predicted to enable cytokine activity. Involved in several processes, including negative regulation of fibroblast proliferation; positive regulation of glial cell proliferation; and response to lipopolysaccharide. Located in extracellular space. Biomarker of cystitis. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); autoimmune disease (multiple); glucose metabolism disease (multiple); leishmaniasis (multiple); and lung disease (multiple). Orthologous to human LTA (lymphotoxin alpha). [provided by Alliance of Genome Resources, Jul 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
