Predicted to enable mRNA binding activity; translation initiation factor activity; and translation initiation factor binding activity. Acts upstream of or within in utero embryonic development; male germ cell proliferation; and male gonad development. Predicted to be located in cytoplasm. Predicted to be part of eukaryotic translation initiation factor 2 complex. Is expressed in several structures, including blastocyst; colon; early embryo; gonad; and liver. Orthologous to human EIF2S2 (eukaryotic translation initiation factor 2 subunit beta). [provided by Alliance of Genome Resources, Apr 2022]
