Background Information

LEO1, also named as RNA polymerase-associated protein LEO1, is a 666 amino acid protein, which belongs to the LEO1 family. LEO1 is a component of the PAF1 complex (PAF1C) which has multiple functions during transcription by RNA polymerase II and is implicated in regulation of development and maintenance of embryonic stem cell pluripotency. The calculated molecular weight of LEO1 is 75 kDa, but the modified LEO1 protein is about 105 kDa (PMID: 15632063).
