Putting together pieces of the LIN28A pathway puzzle
Two recent studies provide mechanistic insights into how LIN28A controls changes in cell fate identity, focusing on either a let-7-independent or let-7-dependent pathway of action involving LIN28A.

Identifying nature’s smallest fractals
Snowflakes, seashells and Romanesco broccoli are striking examples of fractal geometries in nature. A recent study published in Nature defines a set of molecular mechanisms for fractal assembly by identifying a nanometer-scale, regular fractal assembled from a native protein found in blue-green algae that likely arose as an evolutionary accident.

AlphaFold3 takes a step toward decoding molecular behavior and biological computation
AlphaFold 3 represents a breakthrough in predicting the 3D structures of complexes directly from their sequences, offering insights into biomolecular interactions. Extending predictions to molecular behavior and function requires a shift from viewing biomolecules as static 3D structures to dynamic conformational ensembles.

Structure of the poxvirus core
Poxviruses range from deadly smallpox to attenuated vaccinia virus used in vaccines and oncolytic vectors. Despite their broad, if antithetical, effects on humankind, the mechanistic details of poxvirus assembly are not known. Here we discuss advances in revealing the structure of the palisade layer which underlies the viral core morphology.

Structural insights into translocation and tailored synthesis of hyaluronan
Hyaluronan (HA) is an essential glycosaminoglycan. Here, the authors provide mechanistic insights into how HA synthase synthesizes HA and creates a membrane-spanning secretion channel, as well as how channel-lining residues modulate the HA length distribution.

Structural insights into CXCR4 modulation and oligomerization
Here, cryo-electron microscopy structures reveal how the chemokine receptor CXCR4 oligomerizes and how it is regulated by its physiological ligand CXCL12, the small-molecule drug AMD3100 and the monoclonal antibody REGN7663.

How protons shape AMPA receptor structure, function and diffusion at the synapse
The extracellular AMPA receptor N-terminal domain (NTD) affects synaptic strength by tuning receptor diffusion. We reveal that pH fluctuations accompanying synaptic activity alter NTD conformation of the functionally dominant GluA2 subunit, via proton sensing by an NTD histidine residue, thereby increasing gating kinetics and receptor diffusion at the synapse.
