A Na,K-ATPase beta subunit can suppress basal cell carcinogenesis either via its osmoregulatory function to avoid hypotonic stress, or by promoting epithelial polarity and adhesiveness of basal keratinocytes from the overlying outer layer.
Cellular carbon accumulation systems are a fundamental prerequisite for biomineralization to stabilize pH and to supply inorganic carbon for CaCO3 precipitation under changing environmental conditions.
A separation-of-function mutation reveals that a niche ligand receptor Dome functions in spindle orientation during asymmetric stem cell division by directly binding to Eb1, independent of its role in downstream JAK-STAT signaling.
Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.
Quantitative microscopy and theory show that the size of Xenopus laevis egg extract spindles is controlled by a spatially-regulated autocatalytic growth mechanism driven by microtubule-stimulated microtubule nucleation.
