ATP-binding cassette sub-family E member 1 (ABCE1)

Antagonizes the binding of 2-5A (5'-phosphorylated 2',5'-linked oligoadenylates) by RNase L through direct interaction with RNase L and so inhibits its endoribonuclease activity. May play a central role in the regulation of mRNA turnover.

Antagonizes the anti-viral effect of the interferon-regulated 2-5A/RNase L pathway. May act as a chaperone for post-translational events during HIV-1 capsid assembly.
