Enables endopeptidase activity. Involved in several processes, including acute inflammatory response to non-antigenic stimulus; axonal fasciculation; and positive regulation of programmed cell death. Located in several cellular components, including axon; cytosol; and neuronal cell body. Used to study status epilepticus. Biomarker of brain ischemia; endometritis; middle cerebral artery infarction; and prostate carcinoma. Human ortholog(s) of this gene implicated in ovarian carcinoma. Orthologous to human CASP6 (caspase 6). [provided by Alliance of Genome Resources, Apr 2022]
