Has an intrinsic ATPase activity that functions as a sensor of DNA damage or of arrested replication forks and regulates the extent of DNA synthesis. GFP_AEQVI Energy-transfer acceptor. Its role is to transduce the blue chemiluminescence of the protein aequorin into green fluorescent light by energy transfer. Fluoresces in vivo upon receiving energy from the Ca(2+)-activated photoprotein aequorin. Publication Abstract from PubMed The ubiquitin-binding zinc finger (UBZ) is a type of zinc-coordinating beta-beta-alpha fold domain found mainly in proteins involved in DNA repair and transcriptional regulation. Here we report the crystal structure of the UBZ domain of Y-family DNA polymerase (pol) eta and the crystal structure of the complex between the UBZ domain of Werner helicase-interacting protein 1 (WRNIP1) and ubiquitin, crystallized using the green fluorescent protein fusion technique. In contrast to the pol eta UBZ, which has been proposed to bind ubiquitin via its C-terminal alpha helix, ubiquitin binds to a novel surface of WRNIP1 UBZ composed of the first beta strand and the C-terminal alpha helix. In addition, we report the structure of the tandem UBZ domains of Tax1-binding protein 1 (TAX1BP1) and show that the second UBZ of TAX1BP1 binds ubiquitin, presumably in a manner similar to that of WRNIP1 UBZ. We propose that UBZ domains can be divided into at least two different types in terms of the ubiquitin-binding surfaces: the pol eta type and the WRNIP1 type. This article is protected by copyright.
