Explained: Why Furor Over ‘Gain of Function’ is a Giant Red Herring March 11, 2023ByNEWS WIRELeave a Comment Dr Sam Bailey| Is this the smoking gun, or just a stinky red herring? Filed Under:Dr Sam Bailey,Featured,Sci-TechTagged With:BARDA,China,COVID 19,DARPA,fauci,Gain of Function...
Changing the internal ATG does not erase the GOF toxicity, but removes kch's short second product, suggesting that it is not required for channel function in vivo. The mutant phenotypes are better explained by a perturbation of membrane potential instead of internal K+ concentration. Possible ...
Fig. 3: Gain-of-function and dominant-negative mutations are milder than loss-of-function mutations. a Comparison of predicted | ΔΔG | values for gnomAD variants and pathogenic ClinVar mutations from AD genes classified as dominant negative (DN), gain of function (GOF) and haploin...

Consistent with a gain-of-function effect, ectopic expression of the 2 identified SAMD9L mutants decreased cell proliferation relative to wild-type protein. Of the 10 individuals identified who were heterozygous for either SAMD9L mutation, 3 developed MDS upon loss of the mutated SAMD9L allele ...
Recent functional studies demonstrated that ACTA1 K326N and TPM2 Delta K7 mutations were associated with hypercontractility that could be explained by increased myofibrillar Ca2+ sensitivity. A recent structure of the complex of actin and tropomyosin in the relaxed state showed that both these ...
function as epigenetic scaffolds, capable of interacting with chromatin modification complexes, and can also independently bind to a number of transcription factors [16]. Despite their varying lengths, theASXLgenes share a conserved architecture; with each gene comprising a total of 13 exons and 12...
TRPV1 gain of function promoted dendritic cell activation and cytokine production upon inflammatory stimuli, and consequently enhanced dendritic cell-mediated Th17 cell differentiation. Further mechanistic studies showed that TRPV1 gain of function in dendritic cells enhanced activation of calcineurin/nuclear...
Mutations in FUS cause amyotrophic lateral sclerosis (ALS), including some of the most aggressive, juvenile-onset forms of the disease. FUS loss-of-function and toxic gain-of-function mechanisms have been proposed to explain how mutant FUS leads to motor
