Description

2'-5'-oligoadenylate trimer, also known as 2-5A, is a small, naturally occurring molecule that acts as an antiviral agent. It is synthesized in cells in response to viral infection, specifically by the enzyme 2'-5'-oligoadenylate synthetase (OAS). OAS is activated by double-stranded RNA, a molecule found in many viruses. Upon activation, OAS catalyzes the synthesis of 2-5A from ATP. 2-5A then binds to and activates the enzyme RNase L, which degrades viral RNA, inhibiting viral replication. 2-5A plays an important role in the innate immune response to viral infection. It is also being studied for its potential therapeutic applications in treating viral infections. '
