Cytoplasmically sequestered wild-type p53 protein in neuroblastoma is relocated to the nucleus by a C-terminal peptide

Abstract excerpt

Cytoplasmic sequestration of wild-type p53 protein occurs in a subset of primary human tumors including breast cancer, colon cancer, and neuroblastoma (NB). The sequestered p53 localizes to punctate cytoplasmic structures that represent large protein aggregates. One functional consequence of this blocked nuclear access is impairment of the p53-mediated G1 checkpoint after DNA damage. Here we show that cytoplasmic...
