It appears that nuclear DNA ligase III-alpha forms a complex with XRCC1 in the cytoplasm and the subsequent nuclear targeting of the resultant complex is directed by the XRCC1 nuclear localization signal.
Parece que a ADN ligase III-alfa nuclear forma un complexo con XRCC1 no citoplasma e o destino nuclear posterior do complexo resultante está determinado polo sinal de localización nuclear de XRCC1.
