Summary: Predicted to enable adenosylhomocysteinase activity. Acts upstream of or within S-adenosylmethionine cycle. Predicted to be active in cytosol. Is expressed in several structures, including brain; digestive system; immature eye; musculature system; and neural tube. Used to study metabolic dysfunction-associated steatotic liver disease and steatotic liver disease. Human ortholog(s) of this gene implicated in abdominal aortic aneurysm and hypermethioninemia with deficiency of S-adenosylhomocysteine hydrolase. Orthologous to human AHCY (adenosylhomocysteinase).

What's a GeneRIF?

Hepatic steatosis and liver degeneration are prominent features of the ducttrip (dtp) mutant phenotype. Positional cloning identified a causative mutation in the gene encoding S-adenosylhomocysteine hydrolase (Ahcy).

AHCYL1 has a different function from AHCY and plays an important role in embryogenesis by modulating inositol 1,4,5-trisphosphate receptor function for the intracellular calcium release

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.
