Crystal structure of ENL (MLLT1), apo form
Structural highlights
DiseaseENL_HUMAN A chromosomal aberration involving MLLT1 is associated with acute leukemias. Translocation t(11;19)(q23;p13.3) with KMT2A/MLL1. The result is a rogue activator protein. FunctionENL_HUMAN Component of the super elongation complex (SEC), a complex required to increase the catalytic rate of RNA polymerase II transcription by suppressing transient pausing by the polymerase at multiple sites along the DNA.[1] [2] Publication Abstract from PubMedLysine acetylation is an epigenetic mark that is principally recognized by bromodomains, and recently structurally diverse YEATS domains also emerged as readers of lysine acetyl/acylations. Here we present a crystallography-based strategy and the discovery of fragments binding to the ENL YEATS domain, a potential drug target. Crystal structures combined with synthetic efforts led to the identification of a submicromolar binder, providing first starting points for the development of chemical probes for this reader domain family.
