# Structural Mechanisms Controlling Cell-Cycle Gene Expression

> **NIH NIH R01** · UNIVERSITY OF CALIFORNIA SANTA CRUZ · 2020 · $328,200

## Abstract

Project summary
This research project aims to determine how the DREAM and Myb-MuvB (MMB) protein
complexes regulate transcription to control cell proliferation. The conserved MuvB
protein complex either represses or activates cell-cycle genes by timely association with
specific DNA-binding transcription factors including E2F4-p130 (DREAM) and Myb
(MMB). However, the biochemical function of the five protein MuvB complex is unknown.
We propose and will test novel hypotheses for how MuvB associates with chromatin,
how DREAM inhibits transcription by stabilizing chromatin structure, and how Myb
activates gene expression through its association with MuvB. These studies will provide
fundamental new insights regarding how the cell cycle is controlled and will uncover a
novel mechanism for how transcription factors directly modulate gene expression
through nucleosome positioning.
