Summaries for AHCYL2 Gene

Entrez Gene Summary for AHCYL2 Gene

  • The protein encoded by this gene acts as a homotetramer and may be involved in the conversion of S-adenosyl-L-homocysteine to L-homocysteine and adenosine. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2011]

GeneCards Summary for AHCYL2 Gene

AHCYL2 (Adenosylhomocysteinase Like 2) is a Protein Coding gene. Among its related pathways are One carbon pool by folate and Metabolism. GO annotations related to this gene include NAD binding and adenosylhomocysteinase activity. An important paralog of this gene is AHCYL1.

UniProtKB/Swiss-Prot for AHCYL2 Gene

  • May regulate the electrogenic sodium/bicarbonate cotransporter SLC4A4 activity and Mg(2+)-sensitivity. On the contrary of its homolog AHCYL1, does not regulate ITPR1 sensitivity to inositol 1,4,5-trisphosphate (PubMed:19220705).
