Crystal structure of Rad7 and Elc1 complex in yeast
Structural highlights
Function[RAD7_YEAST] Component of the global genome repair (GGR) complex which promotes global genome nucleotide excision repair (GG-NER) which removes DNA damage from nontranscribing DNA. This protein is one of 10 proteins (RAD1, 2,3,4,7,10,14, 16,23 and MMS19) involved in excision repair of DNA damaged with UV light, bulky adducts, or cross-linking agents.[1] [2] [ELOC_YEAST] Prevents degradation of interacting proteins like PCL6 by the proteasome.[3] Publication Abstract from PubMedNucleotide excision repair (NER) is a versatile system that deals with various bulky and helix-distorting DNA lesions caused by UV and environmental mutagens. Based on how lesion recognition occurs, NER has been separated into global genome repair (GGR) and transcription-coupled repair (TCR). The yeast Rad7-Rad16 complex is indispensable for the GGR sub-pathway. Rad7-Rad16 binds to UV-damaged DNA in a synergistic fashion with Rad4, the main lesion recognizer, to achieve efficient recognition of lesions. In addition, Rad7-Rad16 associates with Elc1 and Cul3 to form an EloC-Cul-SOCS-box (ECS)-type E3 ubiquitin ligase complex that ubiquitinates Rad4 in response to UV radiation. However, the structure and architecture of the Rad7-Rad16-Elc1-Cul3 complex remain unsolved. Here, we determined the structure of the Rad7-Elc1 complex and revealed key interaction regions responsible for the formation of the Rad7-Rad16-Elc1-Cul3 complex. These results provide new insights into the assembly of the Rad7-Rad16-Elc1-Cul3 complex and structural framework for further studies.
