2',5'-Oligoadenylate Synthetase MeSH Descriptor Data 2026


MeSH Heading
2',5'-Oligoadenylate Synthetase
Tree Number(s)
D08.811.913.696.445.625
Unique ID
D015088
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D015088
Scope Note
An enzyme that catalyzes the conversion of ATP into a series of (2'-5') linked oligoadenylates and pyrophosphate in the presence of double-stranded RNA. These oligonucleotides activate an endoribonuclease (RNase L) which cleaves single-stranded RNA. Interferons can act as inducers of these reactions.
