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 ...
