Sequence analysis of DD products revealed two cDNAs with identity to known gene products : the catalytic sub-unit of DNA-protein kinase ( DNA-PK(CS) ), and the peroxisomal enzyme 17beta-hydroxysteroid dehydrogenase type IV ( 17beta-HSD IV ).
 protein: peroxisomal enzyme 17beta-hydroxysteroid dehydrogenase type IV; DNA: cDNAs; protein: DD products; protein: DNA-PK(CS); protein: DNA-protein kinase; protein: catalytic sub-unit of DNA-protein kinase; protein: known gene products; protein: catalytic sub-unit; protein: 17beta-HSD IV
