Modulation of estrogen related receptor alpha activity by the kinesin KIF17
Estrogen-related receptor alpha (ERR1) is an orphan nuclear receptor that can bind transcriptional co-activators constitutively. ERR1 expression correlates with poor patient outcomes in breast cancer, heightening interest in this nuclear receptor as a therapeutic target. Because ERR1 has no known regulatory ligand, a major challenge in targeting its activity is to find cellular or synthetic mod...
متن کاملModulation of Receptor Recycling and Degradation by the Endosomal Kinesin KIF16B
Different classes of endosomes exhibit a characteristic intracellular steady-state distribution governed by interactions with the cytoskeleton. We found a kinesin-3, KIF16B, that transports early endosomes to the plus end of microtubules in a process regulated by the small GTPase Rab5 and its effector, the phosphatidylinositol-3-OH kinase hVPS34. In vivo, KIF16B overexpression relocated early e...
متن کاملModulation of kinesin binding by the C-termini of tubulin.
The flexible tubulin C-terminal tails (CTTs) have recently been implicated in the walking mechanism of dynein and kinesin. To address their role in the case of conventional kinesin, we examined the structure of kinesin-microtubule (MT) complexes before and after CTT cleavage by subtilisin. Our results show that the CTTs directly modulate the motor-tubulin interface and the binding properties of...
متن کاملNuclear Migration: Rock and Roll Facilitated by Dynein and Kinesin
The nucleus encounters other organelles as well as high cytoplasmic pressures during its migration within the cell. A new study describes how the action of kinesin and dynein motors is coordinated at the nuclear envelope to rock and roll the nucleus in Caenorhabditis elegans.
متن کاملKinesin-8 motors improve nuclear centering by promoting microtubule catastrophe.
In fission yeast, microtubules push against the cell edge, thereby positioning the nucleus in the cell center. Kinesin-8 motors regulate microtubule catastrophe; however, their role in nuclear positioning is not known. Here we develop a physical model that describes how kinesin-8 motors affect nuclear centering by promoting a microtubule catastrophe. Our model predicts the improved centering of...
