pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Identification of a Key Amino Acid of the Human 5-HT2B Serotonin Receptor Important for Sarpogrelate Binding

open access: yesJournal of Pharmacological Sciences, 2007
Based on radio-ligand binding and molecular modeling studies, sarpogrelate shows a moderate selectivity for 5-HT2B versus 5-HT2A receptors. To confirm the modeling data of sarpogrelate to 5-HT2B receptors predicting interaction of sarpogrelate towards ...

Broad Purpose Vector for Site-Directed Insertional Mutagenesis in Bifidobacterium breve

open access: yesFrontiers in Microbiology, 2021
Members of the genus Bifidobacterium are notoriously recalcitrant to genetic manipulation due to their extensive and variable repertoire of Restriction-Modification (R-M) systems.

Site directed mutagenesis of L-pyrrolysine in dimethylamine methyltransferase [PDF]

open access: yes, 2009
Methanosarcina barkeri is an archaeon and is able to use methylamines as growth substrates for methanogenesis. The methylamine methyltransferases that are involved in initiating methanogenesis from the methylamines have an in-frame amber codon (UAG) that

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

open access: yesMolecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

High-throughput Site-directed Scanning Mutagenesis Using a Two-fragment PCR Approach

open access: yesBio-Protocol, 2020
Site-directed scanning mutagenesis is a useful tool applied in studying protein function and designing proteins with new properties, such as increased stability or enzymatic activity. Creating a systematic library of hundreds of site-directed mutants is
