Summary: Enables serine-type peptidase activity. Involved in several processes, including ceramide metabolic process; pentacyclic triterpenoid metabolic process; and response to herbicide. Predicted to be located in several cellular components, including chromatin; cytoplasmic side of plasma membrane; and mitochondrial intermembrane space. Predicted to be part of CD40 receptor complex and serine-type endopeptidase complex. Predicted to be active in mitochondrion. Used to study transient cerebral ischemia. Biomarker of asphyxia neonatorum; cryptorchidism; middle cerebral artery infarction; and status epilepticus. 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.
