Function 1: Peptidyl-tRNA hydrolase. The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis. Condition: mitochondrion localisation.
Function 2: Apoptosis promoter, binds transcriptional co-repressors (AES and TLE1). Condition: cytoplasmic localisation (during apoptosis).
