Summary
Predicted to enable mRNA binding activity and sequence-specific double-stranded DNA binding activity. Predicted to be involved in RNA metabolic process and positive regulation of macromolecule metabolic process. Predicted to be located in cytosol; nucleolus; and nucleoplasm. Predicted to be active in cytoplasm and nucleus. Orthologous to human LIN28B (lin-28 homolog B). [provided by Alliance of Genome Resources, Jul 2025]
