Predicted to enable mitochondrion targeting sequence binding activity and protein transmembrane transporter activity. Involved in protein import into mitochondrial matrix. Predicted to be located in membrane. Predicted to be part of TIM23 mitochondrial import inner membrane translocase complex. Is an ortholog of human TIMM23 (translocase of inner mitochondrial membrane 23).
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).
