Lipid transfer proteins (LTPs) maintain the specialised lipid compositions of biological membranes, and many are associated with disease. In eukaryotes, they support organellar functions by transporting lipids between compartmentalised metabolic pathways. However, for the majority of the hundreds...
Members of the Omp85 superfamily of outer membrane proteins (OMPs) found in Gram-negative bacteria, mitochondria and chloroplasts are characterized by a distinctive 16-stranded β-barrel transmembrane domain and at least one periplasmic POTRA domain. All previously studied Omp85 proteins promote c...
The bacterial lipid membrane, consisting both of fatty acid (acyl) tails and polar head groups, responds to changing conditions through alteration of either the acyl tails and/or head groups. This plasticity is critical for cell survival as it allows maintenance of both the protective nature of t...
Lipid droplet (LD) growth mechanisms and the roles of LD-associated lipid transfer proteins remain poorly understood. Here, we show that the autophagy lipid transfer protein ATG2A has an anabolic role and promotes LD expansion by transferring diacylglycerol (DAG), and potentially triacylglycerol ...
The induction of endoplasmic reticulum unfolded protein responses (UPRER) contributes to cancer development and progression. We recently linked microbiota-related triggers to the tumor-promoting role of signal transducer activating transcription factor 6 (ATF6) in the colon. Here we substantiate ...
