Predicted to enable kinase activity and tRNA binding activity. Predicted to be involved in phosphorylation; selenocysteinyl-tRNA(Sec) biosynthetic process; and translation. Predicted to act upstream of or within selenocysteine incorporation. [provided by Alliance of Genome Resources, Apr 2022] Among its related pathways are Peptide chain elongation and Metabolism. Gene Ontology (GO) annotations related to this gene include kinase activity and tRNA binding. Specifically phosphorylates seryl-tRNA(Sec) to O-phosphoseryl-tRNA(Sec), an activated intermediate for selenocysteine biosynthesis. nucleus 3
