Structures of Importins,anslocate them to the nucleus (Mattaj and Englmeier 1998; Weis 1998; Görlich and Kutay 1999; Nakielny and Dreyfuss 1999). Macromolecules are targeted to the nucleus by a signal sequence that mediates the interaction with an importin. The founding member of the karyopherin superfamily is the importin

The most striking example of this are the Balbiani ring (BR) mRNPs of . which are composed of an RNA molecule of 35–40 kb in length associated with about 500 protein molecules (Mehlin et al. 1992; reviewed by Daneholt 1997). Among the most abundant RNA-binding proteins found assoc

How Ran Is Regulated,differentiation. Ran is by far the most abundant of these GTPases, and in human HeLa cells it comprises some 0.4% of cellular protein. It regulates import and export of proteins and RNA through the nuclear pores and is involved in the assembly of the mitotic spindle and of the nuclear membrane.
