Predicted to enable RNA binding activity; manganese ion binding activity; and metalloaminopeptidase activity. Predicted to be involved in proteolysis. Predicted to be located in cytoplasm. Is an ortholog of C. elegans R05D3.8; EEED8.4; and EEED8.12. In C. elegans, unc-75 is involved in several processes, including cholinergic synaptic transmission; positive regulation of synaptic transmission; and regulation of alternative mRNA splicing, via spliceosome.
