23417674-5	2013	Likewise, the point mutation of lysine 123 (ubiquitylation site) to arginine of H2B (H2B-K123R) also lowers the association of RNA polymerase II with GAL1, consistent with the role of H2B ubiquitylation in promoting RNA polymerase II association.	Arginine	68-76	H2B clustered histone 21	Homo sapiens	80-83
