What's a GeneRIF?

Structural basis for cytoplasmic dynein-1 regulation by Lis1.
Title: Structural basis for cytoplasmic dynein-1 regulation by Lis1.
these findings indicate that dynein activity is directly switched "on" by Num1, which induces Pac1/LIS1 removal.
Title: The dynein cortical anchor Num1 activates dynein motility by relieving Pac1/LIS1-mediated inhibition.
Lis1 (Pac1) regulates dynein by sterically blocking its mechanochemical cycle.
Title: Lis1 regulates dynein by sterically blocking its mechanochemical cycle.
Here we show that two MAPs-the CLIP-170 homologue Bik1p and the Lis1 homologue Pac1p-interact with several proteins in the sumoylation pathway
Title: The yeast homologue of the microtubule-associated protein Lis1 interacts with the sumoylation machinery and a SUMO-targeted ubiquitin ligase.

Preferred Names: Pac1p

NP_014912.1

Regulator of dynein, involved in intracellular transport; part of the dynein/dynactin pathway; targets dynein to microtubule tips, which is necessary for sliding of microtubules along bud cortex; serves at interface between dynein's ATPase site and its microtubule binding stalk, causing individual dynein motors to remain attached to microtubules for long periods; synthetic lethal with bni1; homolog of human LIS1, mutations in which cause the severe brain disorder lissencephaly
