PTENβ is an alternatively translated isoform of PTEN that regulates rDNA transcription

Abstract

PTEN is a potent tumour suppressor involved in cell growth, proliferation and survival. Here the authors identify an N-terminal extended isoform of PTEN, termed PTENβ that negatively regulates ribosomal DNA transcription and cell proliferation, expanding the pleiotropic functions of the PTEN family.
