Summary: Predicted to enable several functions, including protein homodimerization activity; selenocysteine lyase activity; and vitamin B6 binding activity. Acts upstream of or within several processes, including negative regulation of cellular response to oxidative stress; response to insulin; and selenium compound metabolic process. Predicted to be located in Golgi apparatus. Predicted to be part of catalytic complex. Is expressed in alimentary system; liver; and nervous system. Orthologous to human SCLY (selenocysteine lyase).

What's a GeneRIF?

Studied the role of selenocysteine lyase in amino acid metabolism using knockout mice and a combination of transcriptomics and metabolomics.
Title: Combined Omics Reveals That Disruption of the Selenocysteine Lyase Gene Affects Amino Acid Pathways in Mice.
Loss of Scly within a neuronal sub-population that makes up a small fraction of the hypothalamus produces a phenotype in mice distinguished by reduced weight gain while on high fat diet and resistance to the development of leptin insensitivity.
Title: Agrp-Specific Ablation of Scly Protects against Diet-Induced Obesity and Leptin Resistance.
Selenocysteine lyase regulates energy metabolism via the hypothalamus.
Title: Sexual Dimorphism in the Selenocysteine Lyase Knockout Mouse.
This study showed that Male mice lacking two key genes involved in Se metabolism (Scly(-/-)Sepp1(-/-) mice), selenoprotein P (Sepp1) and Sec lyase (Scly), develop severe neurological dysfunction, neurodegeneration, and audiogenic seizures.
Title: Competition between the Brain and Testes under Selenium-Compromised Conditions: Insight into Sex Differences in Selenium Metabolism and Risk of Neurodevelopmental Disease.
our findings unveil a new metabolic role for Reg3beta in protein nitration and a new biosynthesis control of GPX1 by a completely "unrelated" regenerating protein, Reg3beta, via transcriptional activation of Scly
Title: A novel upregulation of glutathione peroxidase 1 by knockout of liver-regenerating protein Reg3β aggravates acetaminophen-induced hepatic protein nitration.
These findings provide the first in vivo evidence that Scly and Sepp1 work cooperatively to maintain selenoprotein function in the mammalian brain.
Title: Mice lacking selenoprotein P and selenocysteine lyase exhibit severe neurological dysfunction, neurodegeneration, and audiogenic seizures.
The results suggested a dependence of glucose and lipid homeostasis on selenocysteine lyase activity. These findings connect Se and energy metabolism and demonstrate for the first time a unique physiological role of selenocysteine lyase.
Title: Disruption of the selenocysteine lyase-mediated selenium recycling pathway leads to metabolic syndrome in mice.
Scly knockout mice do not display neurological dysfunction comparable to Sepp1 knockout mice.
Title: Absence of selenoprotein P but not selenocysteine lyase results in severe neurological dysfunction.

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.
