Survivin and Aurora Kinase A control cell fate decisions during mitosis
Molecular Oncology, EarlyView.Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

The role of SCF ubiquitin-ligase complex at the beginning of life
Reproductive Biology and Endocrinology, 2019 As the largest family of E3 ligases, the Skp1-cullin 1-F-box (SCF) E3 ligase complex is comprised of Cullins, Skp1 and F-box proteins. And the SCF E3 ubiquitin ligases play an important role in regulating critical cellular processes, which promote ...

CHARACTERIZATION OF THE UBIQUITIN LIGASE, UBE4B, IN ENDOCYTIC TRAFFICKING [PDF]
, 2017 Endocytosis is a process by which cells internalize membrane proteins to remove them from the plasma membrane, allowing cells to regulate the cell surface expression of transmembrane proteins.

Molecular Oncology, EarlyView.A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

The ubiquitin E3/E4 ligase, UBE4A, fine-tunes protein ubiquitylation and accumulation at sites of DNA damage facilitating double-strand break repair [PDF]
, 2018 Double-strand breaks (DSBs) are critical DNA lesions that robustly activate the elaborate DNA damage response (DDR) network. We identified a critical player in DDR fine-tuning - the E3/E4 ubiquitin ligase, UBE4A.

Antibody targeting of E3 ubiquitin ligases for receptor degradation
Nature, 2022 Most current therapies that target plasma membrane receptors function by antagonizing ligand binding or enzymatic activities. However, typical mammalian proteins comprise multiple domains that execute discrete but coordinated activities. Thus, inhibition

Regulation of the CRL4Cdt2 Ubiquitin Ligase and Cell-Cycle Exit by the SCFFbxo11 Ubiquitin Ligase [PDF]
Molecular Cell, 2013 F-box proteins and DCAF proteins are the substrate binding subunits of the Skp1-Cul1-F-box protein (SCF) and Cul4-RING protein ligase (CRL4) ubiquitin ligase complexes, respectively. Using affinity purification and mass spectrometry, we determined that the F-box protein FBXO11 interacts with CDT2, a DCAF protein that controls cell-cycle progression ...

Molecular Oncology, EarlyView.HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

A pathogen type III effector with a novel E3 ubiquitin ligase architecture.
PLoS Pathogens, 2013 Type III effectors are virulence factors of Gram-negative bacterial pathogens delivered directly into host cells by the type III secretion nanomachine where they manipulate host cell processes such as the innate immunity and gene expression.
