hA3G does not traffic to the nucleus. (A) Cellular distribution of AID. C-terminal V5 tagged hAID transfected into HeLa cells localized to the cytoplasm (−LMB). Upon treatment with 20 ng/mL of LMB for 4 h (+LMB) hAID localized to the nucleus. (B) N-terminal HA tagged hA3G transfected into HeLa cells localized in the cytoplasm with and without LMB treatment (+/− LMB) and (C) NLS-hA3G with a SV40 NLS added to the N-terminus remained cytoplasmic with and without LMB treatment (+/− LMB). The upper and lower panels for A–C are two representative fields of the same treatment group. DAPI staining indicates the position of the cell nuclei in each panel.
