Recognition of unmethylated histone H3 lysine 4 links BHC80 to LSD1-mediated gene repression
Fei Lan,Robert E. Collins,Rossella De Cegli,Rossella De Cegli,Roman Alpatov,John R. Horton,Xiaobing Shi,Or Gozani,Xiaodong Cheng,Yang Shi +9 more
TL;DR: These findings couple the function of BHC80 to that of LSD1, and indicate that unmodified H3K4 is part of the ‘histone code’, which raises the possibility that the generation and recognition of the unmodified state on histone tails in general might be just as crucial as post-translational modifications of histone for chromatin and transcriptional regulation.
Journal ArticleDOI
Structural and Sequence Motifs of Protein (Histone) Methylation Enzymes
TL;DR: This review describes structural aspects of methylation of histone lysine residues by two enzyme families with entirely different structural scaffolding (the SET proteins and Dot1p) andmethylation of protein arginine residue by PRMTs.
Journal ArticleDOI
Regulation of Estrogen Receptor α by the SET7 Lysine Methyltransferase
Krithika Subramanian,Da Jia,Priya Kapoor-Vazirani,Doris R. Powell,Robert E. Collins,Dipali Sharma,Junmin Peng,Xiaodong Cheng,Paula M. Vertino +8 more
TL;DR: It is shown that ER is directly methylated at lysine 302 (K302) by the SET7 methyltransferase, raising the possibility that generation, recognition, and removal of modifications within the ER hinge region generate "ER modification cassettes" that yield distinct patterns for signaling downstream events.
Journal ArticleDOI
The ankyrin repeats of G9a and GLP histone methyltransferases are mono- and dimethyllysine binding modules
Robert E. Collins,Jeffrey P. Northrop,John R. Horton,David Y. Lee,Xing Zhang,Michael R. Stallcup,Xiaodong Cheng +6 more
TL;DR: G9a and GLP contain a new type of methyllysine binding module (the ankyrin repeat domains) and are the first examples of protein (histone) methyltransferases harboring in a single polypeptide the activities that generate and read the same epigenetic mark.
Journal ArticleDOI
In Vitro and in Vivo Analyses of a Phe/Tyr Switch Controlling Product Specificity of Histone Lysine Methyltransferases
Robert E. Collins,Makoto Tachibana,Hisashi Tamaru,Kristina M. Smith,Da Jia,Xing Zhang,Eric U. Selker,Yoichi Shinkai,Xiaodong Cheng +8 more
TL;DR: It is found that a Phe at the position equivalent to Phe281 of Neurospora crassa DIM-5 or Phe1205 of human G9a allows the enzyme to perform di and tri-methylation, whereas a Tyr at this position is restrictive, inhibiting tri- methylation and thus yielding a mono- or di-MTase.
