Summary: Enables peptidase activity. Involved in several processes, including cellular response to oxidative stress; negative regulation of type 2 mitophagy; and positive regulation of apoptotic process. Acts upstream of or within several processes, including adult walking behavior; intrinsic apoptotic signaling pathway; and nervous system development. Located in cytoplasmic side of plasma membrane and mitochondrion. Part of CD40 receptor complex. Is expressed in several structures, including gut; nervous system; reproductive system; thymus; and trachea. Human ortholog(s) of this gene implicated in 3-methylglutaconic aciduria type 8; Parkinson's disease; and motor neuron disease. Orthologous to human HTRA2 (HtrA serine peptidase 2).

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.
