Tyrosine phosphorylation of the intracellular domain of LRP1 serves as a molecular switch to regulate cellular cholesterol homeostasis through nuclear hormone receptor-mediated regulation of the cellular cholesterol exporter ABCA1.

Genetic and cell biological analyses reveal a new role of Drp1 in postsynaptic endocytosis during brain development beyond mitochondrial division GTPase.

The conformational dynamics of multidrug resistance protein 1 (MRP1) are tracked in real time by single-molecule fluorescence resonance energy transfer experiments, which elucidate the rate-limiting mechanism of MRP1's transport cycle.

Xrp1 contributes to cell competition as a heterodimer with the Drosophila C/EBP homolog Irbp18 and although rapidly evolving is itself conserved beyond Drosophila.

An activator of branching nucleation by Arp2/3 complex directly synergizes with an activator of linear filament nucleation to initiate assembly of actin networks that drive endocytosis.

In oligodendrocyte progenitor cells, lipid metabolism and peroxisome biogenesis are regulated by the low-density lipoprotein related-receptor-1, and if disrupted, impair proper white matter development and adult repair.

A key cellular process is controlled by altering a balance, rather than through an off/on mechanism.

Induction of the fission of mitochondria-populating sensory axons is shown to be a novel biological action of neurotrophins.

Dhh1, Pat1, and Lsm1 target subsets of cellular mRNAs for decapping via interactions of these regulatory proteins with the C-terminal domain of Dcp2, the catalytic component of the decapping enzyme.

mRNA decapping function in neuronal cells regulates neurosecretion and intertissue signaling, affecting developmental and ageing processes in two model organisms.
