Uniprot Description

LEO1: a component of the PAF1 multifunctional complex involved in initiation and elongation, histone methylation and RNA processing. The PAF1 complex interacts with POLR2A. Overexpression of LEO1 induces cell growth arrest and premature senescence of fibroblasts. The PAF1 complex consists of at least of CDC73, PAF1, LEO1 and CTR9. Interacts with CDC73. Two isoforms of the human protein are produced by alternative splicing.

Protein type: Transcription regulation

Chromosomal Location of Human Ortholog: 15q21.2

Cellular Component: nucleoplasm; nucleolus

Molecular Function: protein binding

Biological Process: histone monoubiquitination; Wnt receptor signaling pathway; negative regulation of myeloid cell differentiation; endodermal cell fate commitment; transcription, DNA-dependent; positive regulation of RNA elongation from RNA polymerase II promoter; stem cell maintenance; histone H2B ubiquitination; positive regulation of mRNA 3'-end processing; mRNA polyadenylation; positive regulation of transcription from RNA polymerase II promoter
