Data for positive selection test and co-evolutionary analysis on mammalian cereblon

Data in Brief, 2019
Cereblon (CRBN) is a substrate recognition subunit of the CRL4 E3 ubiquitin ligase complex, directly binding to specific substrates for poly-ubiquitination followed by proteasome-dependent degradation of proteins.

Silencing Myostatin Using In Vivo Self‐Assembled siRNA Protects Against Cancer‐ and Dexamethasone‐Induced Muscle Atrophy

Advanced Healthcare Materials, EarlyView.
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 ...

UFD-2 is an adaptor-assisted E3 ligase targeting unfolded proteins

Nature Communications, 2018
The U-box ubiquitin ligase UFD-2 is one of the most abundant components of the ubiquitin proteasome system in muscle cells. Here the authors perform in vitro and in vivo experiments and show that UFD-2 has E3 ligase activity and that it ubiquitinates ...

Branched‐Chain α Keto‐Acid Dehydrogenase Kinase‐Mediated AKT Phosphorylation Promotes RCC Tumorigenesis and Drug Resistance

Advanced Science, EarlyView.
This study identifies a novel oncogenic role and a previously unrecognized phosphorylation substrate of BCKDK in RCC, wherein it promotes tumor progression and drug resistance through AKT phosphorylation at both Thr308 and Ser473 sites and activation of AKT/mTOR and AKT/ABCB1 signaling pathways, offering a promising prognostic marker and therapeutic ...

BRCA1 Is a Histone-H2A-Specific Ubiquitin Ligase

Cell Reports, 2014
The RING domain proteins BRCA1 and BARD1 comprise a heterodimeric ubiquitin (E3) ligase that is required for the accumulation of ubiquitin conjugates at sites of DNA damage and for silencing at DNA satellite repeat regions. Despite its links to chromatin,

Multiple regions of E6AP (UBE3A) contribute to interaction with papillomavirus E6 proteins and the activation of ubiquitin ligase activity.

PLoS Pathogens, 2020
The HECT domain E3 ubiquitin ligase E6AP (UBE3A) is critical for the development of human papillomavirus (HPV) associated cancers, the neurodevelopment disorder Angelman Syndrome, and some cases of autism spectrum disorders.

Gal3‐CaN‐Smurf1 Complex Sequestrates FLCN‐FNIPs to Facilitate TFEB Activation in Response to Endomembrane Damage

Advanced Science, EarlyView.
The schematic diagram illustrates the role of the recruitment of Gal3‐CaN‐Smurf1 complex in maintaining lysosomal membrane homeostasis upon damage. On the one hand, the Gal3‐CaN‐Smurf1 complex sequesters FLCN‐FNIPs to block the activation of RagC, where the active form RagC‐GDP is responsible for TFEB phosphorylation.

Structure of a HOIP/E2~ubiquitin complex reveals RBR E3 ligase mechanism and regulation

Nature, 2015
Ubiquitination is a central process affecting all facets of cellular signalling and function. A critical step in ubiquitination is the transfer of ubiquitin from an E2 ubiquitin-conjugating enzyme to a substrate or a growing ubiquitin chain, which is ...

FBXO44 Regulates FOXP1 Degradation Through AURKA‐Dependent Phosphorylation to Promote Colorectal Cancer Progression

Advanced Science, EarlyView.
FBXO44 promotes colorectal cancer progression by targeting FOXP1 for ubiquitin‐mediated degradation. This study reveals a phosphorylation‐dependent mechanism involving AURKA and highlights the FBXO44/FOXP1/Cyclin E2 axis as a potential therapeutic target in colorectal cancer.
