This gene encodes a member of the Argonaute family of proteins which play a role in RNA interference. The encoded protein is highly basic, and contains a PAZ domain and a PIWI domain. It may interact with Dicer1 and play a role in short-interfering-RNA-mediated gene silencing.[6]

Interactions

EIF2C2 has been shown to interact with

• DDX20,[7][8]
• DICER1,[8][9]
• FMRP, FXR1P, FXR2P,[10] and
• TNRC6B.[11]
