Ubiquitin conjugation to histone lysines regulates diverse processes such as gene silencing, transcriptional elongation, and DNA repair. This factor is also expressed in the olfactory and dentate gyrus granule cell lineages, labeling both their earliest precursors within the neural tube and remaining expressed in the fully mature neurons. The versatility of this mode of regulation suggests that it likely plays an important contribution in ensuring the developmental plasticity that is essential for plant survival. Recent studies in the Heintz laboratory have established that the histone gene transcription factors undergo a complex program of phosphorylation during the cell cycle that eventually leads to their inactivation in mitosis. Most of the work in the lab … Professor Department of Organismic and Evolutionary Biology Harvard University … Over the past decade, studies involving the model plant system Arabidopsis have identified several intermediates that link the perception of signals with physiological outputs.

Even less is understood concerning the mechanisms by which plants integrate multiple signals to ensure appropriate developmental responses to their constantly changing environment. Dr. Heintz's laboratory has established that transcriptional induction of histone gene expression involves coordinate activation of a set of transcription factors (Oct1, H1TF2, H1TF1,H4TF2) that interact with subtype specific consensus sequences within the histone gene promoters. Although these two transcription factors are both involved in cell cycle regulation, their primary structure and biochemical properties are entirely different. Identification of these mechanisms, and analysis of their functions throughout the central nervous system (CNS), are major priorities of the Heintz laboratory.One strategy for investigation of molecular mechanisms controlling cerebellar development is the isolation and investigation of specific genes that mark critical events in its formation. )Cerebellar Dysfunction: Positional Cloning of Murine Neurologic Mutant Genes.
