RANBP9: Proteins and Enzymes

Just as heat shock proteins function as chaperones for exposed hydrophobic patches, importins act as chaperones for exposed basic domains, and it is suggested that this represents a major and general cellular function of importins (1). RanBP9, a novel interacting protein, was localized within the centrosome throughout the cell cycle. Overexpression of RanBP9 produced multiple spots which were colocalized with gamma-tubulin and acted as ectopic microtubule nucleation sites, resulting in a ...
