Protein kinase B phosphorylates AHNAK and regulates its subcellular localization

AHNAK is a ubiquitously expressed giant phosphoprotein that was initially identified as a gene product subject to transcriptional repression in neuroblastoma. AHNAK is predominantly nuclear in cells of nonepithelial origin, but is cytoplasmic or associated with plasma membrane in epithelial cells. In this study we show that the extranuclear localization of AHNAK in epithelial cells depends on t...

Aurora B Phosphorylates Centromeric MCAK and Regulates Its Localization and Microtubule Depolymerization Activity

BACKGROUND Sister kinetochores must bind microtubules in a bipolar fashion to equally segregate chromosomes during mitosis. The molecular mechanisms underlying this process remain unclear. Aurora B likely promotes chromosome biorientation by regulating kinetochore-microtubule attachments. MCAK (mitotic centromere-associated kinesin) is a Kin I kinesin that can depolymerize microtubules. These t...

The double-time protein kinase regulates the subcellular localization of the Drosophila clock protein period.

The Period (PER), Timeless (TIM), and Double-Time (DBT) proteins are essential components of one feedback loop in the Drosophila circadian molecular clock. PER and TIM physically interact. Coexpression of PER and TIM promotes their nuclear accumulation and influences the activity of DBT: although DBT phosphorylates and destabilizes PER, this is suppressed by TIM. Experiments using Drosophila ce...

Carboxyl-terminal phosphorylation regulates the function and subcellular localization of protein kinase C betaII.

Protein kinase C is processed by three phosphorylation events before it is competent to respond to second messengers. Specifically, the enzyme is first phosphorylated at the activation loop by another kinase, followed by two ordered autophosphorylations at the carboxyl terminus (Keranen, L. M., Dutil, E. M., and Newton, A. C. (1995) Curr. Biol. 5, 1394-1403). This study examines the role of neg...
