Serine/threonine-protein kinase BUR1; Serine/threonine-protein kinase involved in transcription regulation. Phosphorylates the UBC2/RAD6 ubiquitin- conjugating enzyme (E2), leading to monoubiquitination of histone H2B and the silencing of telomeric-associated genes. Also required for histone H3 methylation. Necessary for the recovery from pheromone-induced growth arrest in the cell cycle G1 phase (By similarity) (667 aa)
