FAMILY

CATEGORY

transcription factor

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus

basic FUNCTION	directly involved in transcription elongation via histone H2B ubiquitination and histone H3 methylation
	PAF1 and the PAF complex are key regulators of cell-cycle progressionb
	acts in chromatin transcription elongation both independently and cooperatively with TCEA2 and TCEA3
	likely plays an important role in the complex processes of embryonic stem cell growth and terminal differentiation
	important role in rRNA synthesis
	regulates the developmental potential of the lateral plate mesoderm and is required cell autonomously for the specification of cardiac precursors
	involved in the regulation of transcriptional elongation and has oncogenic potential
	influences gene expression by regulating chromatin structure and the recruitment of RNA-processing factors during transcription elongation

CELLULAR PROCESS

nucleotide, transcription, elongation

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component	complexing with LEO1, CDC73, SH2BP1
	part of the PAF1 complex (PAF1C) implicated in transcription-associated events
	PAF1 and LEO1 subunits form a tightly associated heterodimer through antiparallel beta-sheet interactions 8)

INTERACTION

DNA

RNA

small molecule

protein	cooperative binding with RNA polymerase II
	UBE2E1, RNF20/40, and the PAF1 complex are recruited to transcriptionally active genes
	interacting with TCEA2
	associated with promoters of genes important for pluripotency, potentially maintaining an active chromatin structure
	PAF1 complex synergizes with MLL fusion proteins at HOX loci to promote leukemogenesis
