Disruption Of The Dream Complex Results In Cell Cycle Deregulation, Hayley C. Walston

Theses and Dissertations

The Dimerization Partner, Rb-like, E2F, And MuvB (DREAM) complex was identified in humans due to homology of the genes involved in the D. melanogaster dREAM complex. It assembles during cellular arrest, or G0, to function as a transcriptional repressor of cell cycle genes. It is known that phosphorylation of LIN52 at serine 28 is necessary for the critical DREAM forming interaction between LIN52 and the pocket protein p130. Our laboratory has previously shown that gene editing of LIN52 to replace serine 28 with alanine (S28A) prevents phosphorylation by the kinase DYRK1A and inhibits DREAM formation. Here we have confirmed this …
