Summary: 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, Nov 2024]
Expression: Ubiquitous expression in thymus adult (RPKM 18.9), lung adult (RPKM 13.3) and 28 other tissues See more

What's a GeneRIF?

SZT2 maintains hematopoietic stem cell homeostasis via nutrient-mediated mTORC1 regulation.
Title: SZT2 maintains hematopoietic stem cell homeostasis via nutrient-mediated mTORC1 regulation.
SZT2 has a central role in dictating GATOR-dependent nutrient sensing by promoting lysosomal localization of SZT2-orchestrated GATOR complex, and reveal an unexpected function of lysosome-located GATOR2 in suppressing mTORC1 signalling through SESN recruitment
Title: SZT2 dictates GATOR control of mTORC1 signalling.
in mice that lack SZT2, mTORC1 signalling is increased in several tissues, including in neurons in the brain
Title: KICSTOR recruits GATOR1 to the lysosome and is necessary for nutrients to regulate mTORC1.
While the biological function of Szt2 remains unknown, its high conservation, unique structure and effect on seizure threshold suggest that it serves an important role in the central nervous system.
Title: Szt2, a novel gene for seizure threshold in mice.

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.
