Involved in negative regulation of TORC1 signaling; regulation of superoxide dismutase activity; and response to nutrient levels. Acts upstream of or within central nervous system development; pigmentation; and post-embryonic development. Located in peroxisome. Is expressed in several structures, including central nervous system; heart; lung; metanephros; and spleen. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 18. Orthologous to human SZT2 (SZT2 subunit of KICSTOR complex). [provided by Alliance of Genome Resources, Apr 2022]
