Molecular biology

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules such as nucleic acids and proteins that carry out the biological processes essential for the cells functions and maintenance.

In vivo single-molecule analysis reveals COOLAIR RNA structural diversity

The structures of single COOLAIR RNA isoforms change in abundance and shape in response to external conditions; structural mutation of these isoforms altered FLC expression and flowering time, consistent with a regulatory role of the COOLAIR structure in FLC transcription.

Structural keys unlock RAS–MAPK cellular signalling pathway

Activation of the RAF protein is key to the RAS–MAPK signalling pathway, and involves the SMP protein complex. Structures for SMP shed light on the process, and suggest fresh targets for anticancer drug discovery.

Engineered Cas13 variants with minimal collateral RNA targeting

The application of CRISPR–Cas13 for targeted RNA degradation is hindered by the existence of collateral effects induced by Cas13. We screened hundreds of engineered Cas13 variants using a convenient and sensitive reporter system and obtained several variants with markedly reduced collateral activity and efficient on-target activity, suitable for in vivo applications.

Landscape of somatic mutations in aging human heart muscle cells

Using single-cell whole-genome sequencing, we identified and characterized the landscape of somatic single-nucleotide variants (sSNVs) in single cardiomyocytes from individuals across the human lifespan. Aged cardiomyocytes were found to have a higher burden of sSNVs and show mutational signatures that suggest failed repair of oxidative DNA damage.

Filling in the blanks: how the C-strand catches up to the G-strand at replicating telomeres using CST

CST is both an ssDNA-binding complex and a DNA Pol-α/primase cofactor that coordinates the switch from G-strand elongation to C-strand fill-in during telomere maintenance. Four papers in Nature Structural & Molecular Biology and Nature provide transformative insights into CST activity, providing a platform to understand lagging-strand synthesis genome wide.
