Aldehyde dehydrogenase 1B1-specific small-molecule inhibitors are identified that block the growth of colon cancer spheroids and organoids and are shown to potentially regulate mitochondrial metabolism and ribosomal function.

Sea stars and sea cucumbers biosynthesize protective glycosylated steroids and triterpenes via divergent oxidosqualene cyclases (OSCs) that produce these distinct saponins in different species as well as in different tissues of a single species.

Using combined methods of modern chemical protein synthesis and structural biology, Ai et al. found a crosstalk mechanism of histone modifications, by which H2BK34ub stimulates the activity of the H3K79 methyltransferase Dot1L through inducing nucleosome distortion.

Antigen loading onto class I major histocompatibility complex (MHC-I) proteins relies on chaperones and protein flexibility. Researchers now provide new insight into the process, especially for the intriguing ‘non-classical’ MHC-I protein MR1, with implications for fundamental immunology and the development of novel immunotherapies.

The marine compound microcolin B stimulates the Hippo pathway and selectively kills YAP-dependent cancer cells by inhibiting phosphatidylinositol transfer protein and depleting plasma membrane phosphatidylinositol-4-phosphate.

Biochemical and structural approaches define how the chaperone TAPBPR interacts with MR1 molecules, including empty and ligand-loaded MR1, and facilitates presentation of metabolite-derived antigen ligands by MR1 complexes.

Comprehensive structural biology analysis of seven members of the S1 carbohydrate sulfatase family derived from human gut microbiome Bacteroides reveals mechanisms of glycan recognition and sulfate hydrolysis.
