Phospho-Mutant Activity Assays Provide Evidence for the Negative Regulation of Transcriptional Regulator PRE1 by Phosphorylation.

International journal of molecular sciences - 2 Dec 2020

Wang Minmin, Tian Yanchen, Han Chao, Zhou Chuanen, Bai Ming-Yi, Fan Min

Abstract excerpt

The PACLOBUTRAZOL-RESISTANCE (PRE) gene family encodes a group of atypical helix-loop-helix (HLH) proteins that act as the major hub integrating a wide range of environmental and hormonal signals to regulate plant growth and development. PRE1, as a positive regulator of cell elongation, activates HBI1 DNA binding by sequestering its inhibitor IBH1. Furthermore, PRE1 can be phosphorylated at Ser-46 and Ser-67, but...
