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]

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.
