Project description:DOT1L as methyltransferase of H3K79 is implicated in brian development. Here, we further defined DOT1L function within the granular neurons during cerebellar development using ChIP-seq of H3K79 dimethylation of isolated cerebellar granular neurons and progenitors. Thereby we compared samples treated with a DOT1L inhibitor versus DMSO treated cells. The data sets reveals new important targets of DOT1L, which ensure a correct development of the cerebellum.
Project description:During exocytosis, a Ca2+ increase arises in close vicinity of secretory granules which is strictly prevented in resting cells. Granular Ca2+ homeostasis and its role in granular exocytosis are not well understood.
