Predicted to enable polyubiquitin modification-dependent protein binding activity; proteasome binding activity; and ubiquitin binding activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process. Predicted to be located in cytosol and nucleoplasm. Expressed in dorsal nerve cord; head; neurons; ventral nerve cord; and vulva. Is an ortholog of human RAD23A (RAD23 homolog A, nucleotide excision repair protein).
Predicted to enable heme binding activity; oxygen binding activity; and oxygen carrier activity. Predicted to be involved in oxygen transport. Expressed in head neurons; lateral nerve cord; ventral cord neurons; and ventral nerve cord.
