Inducing presomitic mesoderm (PSM)-fated ES cells clarified that Ripply2 directly interacts with Tbx6 and degrades Tbx6 in proteasome-ubiquitin pathway by recruiting the 26S proteasome, which is a PSM-specific event to define the segment border during mouse somitogenesis.
A discovery of two previously unknown, molecularly distinct fields of cardiac progenitors in zebrafish provides evidence for cardiac laterality prior to the emergence of cardiac septation and allows novel insights into cardiac development and disease.
Biochemical tags can be easily knocked into endogenous genes in mammalian stem cells using optimised and scalable protocols that will enable annotation of protein levels, localisation and interaction partners.
Human LINE-1 retrotransposition is found to critically depend on the rapidly evolving N-terminal sequence of the LINE-1 ORF1 protein and on the metastability of its coiled coil domain, indicating uncharacterized steps in LINE-1 retrotransposition.
Selective synapse formation in a retinal motion-sensitive circuit is orchestrated by starburst amacrine cells, which use homotypic interactions to initiate formation of a dendritic scaffold that recruits projections from circuit partners.
