SV40 large T antigen NLS is from Large T antigen residue 47 to 55, enables protein import into cell nucleus.

SV40 large tumor-antigen (T-ag) nuclear import is enhanced by the protein kinase CK2 (CK2) site (Ser111Ser112) flanking the nuclear localization sequence (NLS). T-ag NLS can enhance nuclear import, despite the fact that PK-C has been shown to inhibit nuclear import of proteins such as lamin B2.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.
