We demonstrate that E6AP regulates p27 (zeige PAK2 Antikörper) expression by inhibiting its transcription in an E2F1 (zeige E2F1 Antikörper)-dependent manner. Concomitant knockdown of E6AP and p27 (zeige PAK2 Antikörper) partially restores PC cell growth, supporting the contribution of p27 (zeige PAK2 Antikörper) to the overall effect of E6AP on prostate tumorigenesis.
novel IVS15-1G>C and c.2540 C>T mutations of the UBE3A gene probably underlie the AS in the two families
Findings show neuronal overexpression of Ube3a isoform 2 causes phenotypes translatable to neurodevelopmental disorders.
This study demonstrate the importance of the N-terminal domain of full length E6AP for diubiquitin (zeige UBD Antikörper) chain specificity.
our data demonstrates that E6AP facilitates ubiquitination and subsequent degradation of G-CSFR (zeige CSF3R Antikörper) leading to attenuation of its downstream signaling and inhibition of granulocytic differentiation.
Novel intragenic deletions within the UBE3A gene have been reported in two unrelated patients with Angelman syndrome.
Data suggest ordered binding of UBCH7 (zeige UBE2L3 Antikörper)-ubiquitin to E6AP Site 1 (for E6AP-Cys820/ubiquitin thioester formation) and E6AP Site 2 (for subsequent chain elongation); proximal indexation accounts for symmetric structure of E6AP, requirement for oligomerization in polyubiquitin (zeige UBB Antikörper) chain formation, and mechanistic rationale for Cys820-ubiquitin thioester as platform in chain assembly. (UBCH7 (zeige UBE2L3 Antikörper) = ubiquitin-conjugating enzyme UBCH7 (zeige UBE2L3 Antikörper))
E6AP (UBE3A) abundance is down-regulated in a proportion of NSCLC (non-small cell lung (zeige CDKN2B Antikörper)cancer) patients, and this correlates with low p16INK4a in tumors and worse overall survival.
study has broad implications for human disorders associated with UBE3A gain or loss of function and suggests that dysfunctional UBE3A might affect additional proteins and pathways that are sensitive to proteasome activity
We found that KD of E6AP attenuates cancer cell growth by promoting cellular senescence in vivo, which correlates with restoration of tumor suppression by PML (zeige PML Antikörper).
Using in vivo patch-clamp electrophysiology, study measured the visually evoked responses to square-wave drifting gratings in L2/3 regular-spiking (RS) neurons in control mice, Ube3a-deficient mice (Angelman syndrome model), and mice in which Ube3a was conditionally reinstated in GABAergic neurons; found that Ube3a-deficient mice exhibited enhanced pyramidal neuron excitability in vivo as well as weaker orientation tuning
Findings suggest that aberrant function of Ube3a could influence the progression of AD and restoring normal level of Ube3a might be beneficial for AD.
Encephalomyocarditis virus (EMCV) 3C protease accumulates to higher levels in EMCV-infected E6AP knockdown cells than in control cells, indicating a role for E6AP in in vivo 3C protease concentration regulation.
The expression of three tumor suppressor genes encoded in the INK4/ARF locus (p15(INK4b (zeige CDKN2B Antikörper)), p16(INK4a), and p19(ARF)) was decreased in E6AP(-/-) embryo fibroblasts.
Maternal loss of Ube3a affects nociception via a central, but not peripheral mechanism.
Our findings suggest that UBE3A may act locally to regulate individual synapses while also mediating global, neuronwide influences through the regulation of gene transcription
treatment of topotecan, a brain-penetrating topoisomerase 1 (zeige TOP1 Antikörper) inhibitor, to HD transgenic mouse considerably improved its motor behavioural abnormalities. Finally, we show that topotecan treatment to HD mouse not only inhibits the expression of transgenic mutant huntingtin (zeige HTT Antikörper), but also at the same time induces the expression of Ube3a
We report that mice with maternally-inherited deletions of Ube3a that models Angelman syndrome show an increased social preference/interaction.
increasing UBE3A in the nucleus downregulates the glutamatergic synapse organizer Cbln1 (zeige CBLN1 Antikörper), which is needed for sociability in mice
Negative regulation of Tkv by Ube3a was conserved in mammalian cells. These results reveal a critical role for Ube3a in regulating NMJ synapse development by repressing BMP (zeige TGFb Antikörper) signaling. This study sheds new light onto the neuronal functions of UBE3A and provides novel perspectives for understanding the pathogenesis of UBE3A-associated disorders.
Data indicate that E3 ligase called ube3 (dube3a) is required for brain development as mutants have defective mushroom bodies.
Rpn10 is targeted for degradation by Ube3a.
In Drosophila melanogaster the human homologue ube3a regulates the actin cytoskeleton and neuronal homeostasis.
MeCP2 and E6AP play a role in the transcriptional control of common target gene expression.
Ube3a regulates serotonin and dopamine synthesis in the fly brain by increasing GTP cyclohydrolase I (zeige GCH1 Antikörper) activity.
dube3a null mutants appear normal externally, but display abnormal locomotive behavior and circadian rhythms, and defective long-term memory; overexpression in the nervous system caused locomotion defects, dependent on the ubiquitin ligase activity
Overexpression of dUBE3A decreased dendritic branching.
In the skeletal muscle of neonate pigs, both NECD (zeige NDN Antikörper) and SNRPN (zeige SNRPN Antikörper) were maternally imprinted, while UBE3A was not imprinted.
This gene encodes an E3 ubiquitin-protein ligase, part of the ubiquitin protein degradation system. This imprinted gene is maternally expressed in brain and biallelically expressed in other tissues. Maternally inherited deletion of this gene causes Angelman Syndrome, characterized by severe motor and intellectual retardation, ataxia, hypotonia, epilepsy, absence of speech, and characteristic facies. The protein also interacts with the E6 protein of human papillomavirus types 16 and 18, resulting in ubiquitination and proteolysis of tumor protein p53. Alternative splicing of this gene results in three transcript variants encoding three isoforms with different N-termini. Additional transcript variants have been described, but their full length nature has not been determined.
