Predicted to enable poly(A) binding activity; protein kinase activity; and small molecule binding activity. Predicted to be involved in protein phosphorylation and regulation of mRNA stability. Is an ortholog of C. elegans pek-1. In C. elegans, pek-1 is involved in PERK-mediated unfolded protein response; nematode larval development; and regulation of macromolecule metabolic process.
