Summary: Predicted to enable cytokine activity. Involved in positive regulation of interleukin-12 production. Acts upstream of or within gene expression; lymph node development; and skin development. Predicted to be located in plasma membrane. Predicted to be active in extracellular space. Is expressed in several structures, including brain; hemolymphoid system; liver; lung; and reproductive system. Orthologous to human LTB (lymphotoxin beta).

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.
