The ubiquitin–protein ligase activity of Hdm2 is inhibited by nucleic acids
The proto‐oncoprotein Hdm2 is a member of the RING finger‐type family of ubiquitin–protein ligases E3. The RING finger domain is assumed to mediate the specific interaction of an E3 with its cognate ubiquitin‐conjugating enzyme E2, which catalyzes the covalent attachment of ubiquitin to substrate proteins. In addition, the RING finger domain of Hdm2 is

Pirh2, a p53-Induced Ubiquitin-Protein Ligase, Promotes p53 Degradation [PDF]
The p53 tumor suppressor exerts anti-proliferative effects in response to various types of stress including DNA damage and abnormal proliferative signals. Tight regulation of p53 is essential for maintaining normal cell growth and this occurs primarily through posttranslational modifications of p53. Here, we describe Pirh2, a gene regulated by p53 that

Moyamoya Disease and the Risk of Parkinson's Disease
ABSTRACT Objectives Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the progressive narrowing of arteries at the base of the brain, forming abnormal collateral vascular networks. While vascular parkinsonism is noted in MMD, its link to Parkinson's disease (PD) has not been explored.

Parkin function in Parkinson's disease [PDF]
Parkinson's disease (PD) is the second most common neurodegenerative disease, and is characterized by involuntary shaking, muscle rigidity, and the progressive loss of dopaminergic neurons.

The study reveals that RRP9 is abnormally highly expressed in ESCC tissues and is closely associated with poor prognosis in patients. Furthermore, it is found that RRP9 promotes ESCC progression through enhancing the E2F1‐mediated transcriptional regulation of CDK1.

Necdin promotes ubiquitin-dependent degradation of PIAS1 SUMO E3 ligase. [PDF]
Necdin, a pleiotropic protein that promotes differentiation and survival of mammalian neurons, is a member of MAGE (melanoma antigen) family proteins that share a highly conserved MAGE homology domain.

SUMOylation inhibits FOXM1 activity and delays mitotic transition [PDF]
The forkhead box transcription factor FOXM1 is an essential effector of G2/M-phase transition, mitosis and the DNA damage response. As such, it is frequently deregulated during tumorigenesis. Here we report that FOXM1 is dynamically modified by SUMO1 but

This study reports an in vivo self‐assembled siRNA strategy that enables the liver to generate small extracellular vesicles (sEVs) tagged with a muscle‐targeting peptide (MSP) and naturally loaded with myostatin (MSTN)‐siRNA. These MSP‐tagged sEVs are systemically delivered to skeletal muscle, efficiently silence MSTN, promote muscle hypertrophy, and ...

The proteasome lid triggers COP9 signalosome activity during the transition of Saccharomyces cerevisiae cells into quiescence. [PDF]
The class of Cullin–RING E3 ligases (CRLs) selectively ubiquitinate a large portion of proteins targeted for proteolysis by the 26S proteasome. Before degradation, ubiquitin molecules are removed from their conjugated proteins by deubiquitinating enzymes,
