These results suggest that the temporal control of c-Jun and c-Fos may be regulated through the ubiquitinylation pathways , and the ubiquitinylation of c-Jun and c-Fos may in turn be regulated in response to the heterodimerization between them and the cooperation between E220K and E3 mediated polyubiquitinylation .
 ( protein: c-Fos, None) , ( protein: c-Jun, None) , ( protein: E220K, None) , ( protein: c-Fos, None) , ( protein: c-Jun, None)
