Summary: Predicted to enable cysteine-type endopeptidase activity involved in apoptotic signaling pathway. Acts upstream of or within regulation of cysteine-type endopeptidase activity involved in apoptotic process and symbiont-mediated activation of host apoptosis. Predicted to be part of CD95 death-inducing signaling complex. Predicted to be active in cytoplasm. Is expressed in several structures, including axis; germ ring; intestine; male organism; and nervous system. Human ortholog(s) of this gene implicated in several diseases, including autoimmune lymphoproliferative syndrome type 2B; breast cancer; endocrine gland cancer (multiple); esophagus adenocarcinoma; and lung cancer. Orthologous to human CASP8 (caspase 8). [provided by Alliance of Genome Resources, Dec 2024]

Targeted gene knockdown of TNFRSF1B in zebrafish embryos results in the induction of a caspase-8, caspase-2 and P53-dependent apoptotic program in endothelial cells that bypasses caspase-3.
Title: TNF receptors regulate vascular homeostasis in zebrafish through a caspase-8, caspase-2 and P53 apoptotic program that bypasses caspase-3.
These results show that zebrafish casp8 has a structure and function similar to mammalian CASP8 orthologs and the role of caspase-8 in the apoptotic signal pathway has been conserved over at least 450 million years of vertebrate evolution.

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.
