Proteomics research requires methods to characterize the expression and function of proteins in complex mixtures. Toward this end, chemical probes that incorporate known affinity labeling agents have facilitated the activity-based profiling of certain enzyme families. To accelerate the discovery of proteomics probes for enzyme classes lacking cognate… (More)
A new method for in-cell protein labeling was developed. This method employed a binding-induced nucleophilic reaction between the Cys-appended His-tag and the Ni(II)-NTA containing an α-chloroacetamide. Using this method, not only labeling of His-tag fused proteins but also the detection of a protein-protein interaction was achieved inside living cells.
We have developed a new fluorescent binuclear Zn(II) complex for the detection of neurofibrillary tangles (NFTs) of hyperphosphorylated tau proteins, a representative hallmark of Alzheimer's disease (AD). The probe 1 incorporates a fluorescent BODIPY unit and two Zn(II)-2,2'-dipicolylamine (Dpa) complexes as a binding site for phosphorylated amino acid… (More)
Hydropersulfide (R–SSH) is an important class of reactive sulfur species (RSS) involved in a variety of physiological processes in mammals. A fluorescent probe capable of real-time detection of hydropersulfide levels in living cells would be a versatile tool to elucidate its roles in cell signalling and redox homeostasis. In this paper, we report a… (More)
Chronic kidney disease (CKD) is a global health problem, and novel therapies to treat CKD are urgently needed. Here, we show that inhibition of G0/G1 switch 2 (G0s2) ameliorates renal inflammation in a mouse model of CKD. Renal expression of chemokine (C-C motif) ligand 2 (Ccl2) was increased in response to p65 activation in the kidneys of wild-type 5/6… (More)
