Crystal structure of the Bre1-Lge1 complex

Structural highlights

9m3i is a 5 chain structure with sequence from Saccharomyces cerevisiae S288C. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	X-ray diffraction, Resolution 3.5Å
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

BRE1_YEAST E3 ubiquitin-protein ligase that mediates monoubiquitination of histone H2B to form H2BK123ub1 in association with the E2 enzyme RAD6/UBC2. H2BK123ub1 gives a specific tag for epigenetic transcriptional activation, elongation by RNA polymerase II, telomeric silencing, and is also a prerequisite for H3K4me and H3K79me formation. It thereby plays a central role in histone code and gene regulation. Also modulates the formation of double-strand breaks during meiosis.^[1] ^[2] ^[3] ^[4] ^[5]
