Modification of proteins by ubiquitination plays important roles in various cellular processes. During this process, the target specificity is determined by ubiquitin ligases. Here we identify RNF220 (RING finger protein 220) as a novel ubiquitin ligase for Sin3B. As a conserved RING protein, RNF220 can bind E2 and mediate auto-ubiquitination of itself.(More)
Alzheimer’s disease (AD) is characterized by amyloid deposition, tangle formation as well as synapse loss. Synaptic abnormalities occur early in the pathogenesis of AD. Identifying early synaptic abnormalities and their underlying mechanisms is likely important for the prevention and treatment of AD. We performed in vivo two-photon calcium imaging to(More)
Microglia are known as resident immune cells in the brain. β-amyloid (Aβ) plaques in the brain of Alzheimer’s disease (AD) are surrounded by microglia, but whether and how microglia affect the formation and maintenance of plaques remains controversial. We depleted microglia by injecting diphtheria toxin (DT) in CX 3 CR1 CreER/+ :R26 DTR/+ (CX 3 CR1-iDTR)(More)
A full-length cDNA clone encoding an 866 bp-length glutathione peroxidase protein (NnGPX) was isolated from lotus (Nelumbo nucifera L.). The deduced amino acid sequence of the NnGPX gene had significant homology with ATGPX6. A 3D structural model of the NnGPX was constructed by homology modeling. The cloned NnGPX gene was expressed in Escherichia coli, and(More)
