May facilitate double-stranded RNA-regulated gene expression at the level of post-transcription. Can act as a translation inhibitory protein which binds to coding sequences of acid beta-glucosidase (GCase) and other mRNAs and functions at the initiation phase of GCase mRNA translation, probably by inhibiting its binding to polysomes.
Phosphorylated by RNA-dependent protein kinase (EIF2AK2).
Methylated by protein arginine N-methyltransferase 1.
Arg-609 is dimethylated, probably to asymmetric dimethylarginine.

Can regulate protein arginine N-methyltransferase 1 activity. May regulate transcription of the IL2 gene during T-cell activation. Can promote the formation of stable DNA-dependent protein kinase holoenzyme complexes on DNA.
