MetabolomicsATP-binding Cassette Sub-family C Member 5 (ABCC5) Functions as an Efflux Transporter of Glutamate Conjugates and Analogs
The ubiquitous efflux transporter ATP-binding cassette sub-family C member 5 (ABCC5) is present at high levels in the blood-brain barrier, neurons and glia, but its function is not known. Untargeted metabolomic screens revealed that Abcc5-/- mice accumulate endogenous glutamate conjugates in several...

TranscriptomicsCotranslational signal independent SRP preloading during membrane targeting
Cotranslational targeting into the endoplasmic reticulum (ER) by the Signal Recognition Particle (SRP) is a key event determining polypeptide fate in eukaryotic cells. Here, we globally define the principles and mechanisms of SRP binding and ER targeting in vivo. Cotranslational targeting through SR...

ProteomicsRole of the internal disulfide bond in altering the binding properties of SARS-CoV-2 membrane binding peptide to lipid bilayer
The SARS-CoV-2 spike protein’s membrane-binding domain bridges the viral and host cell membrane, a critical step in triggering membrane fusion. we investigate how the SARS-CoV-2 spike protein interacts with host cell membranes, focusing on a membrane-binding peptide (MBP) located near the TMPRSS2 cl...

TranscriptomicsThe antimicrobial peptide-sensing system aps of Staphylococcus aureus
Staphylococcus aureus is a leading cause of hospital-associated infections. In addition, highly virulent strains of methicillin-resistant S. aureus (MRSA) are currently spreading outside health care settings. Survival in the human host is largely defined by the ability of S. aureus to resist mechani...

ProteomicsStructure of an essential inner membrane protein-LPS complex identifies a novel anti-microbial peptide
Lipopolysaccharide (LPS) resides in the outer membrane (OM) of Gram-negative bacteria where it is responsible for barrier function and immune modulation. LPS is the target of polymyxins, last-resort antibiotics whose clinical use is threatened by increasing resistance. Steps in LPS biogenesis are ...
