Karyopherin-mediated import of integral inner nuclear membrane proteins
Article Abstract:
Integral inner nuclear membrane (INM) proteins in cells are confirmed to possess basic sequence motifs resembling 'classical' nuclear localization signals, which mediate direct binding to karyopherin-alpha and are essential for the passage of integral membrane proteins to the INM. Also, karyopherin-alpha, karyopherin-beta1, and the Ran GTPase cycle are required for INM targeting, indicating similarities between mechanisms governing INM targeting and soluble nuclear transport.

Taking a turn into the nucleus
Article Abstract:
Studies reveal that the transmembrane proteins in yeast get into the inner nuclear membrane (INM) by a receptor-mediated transport mechanism. The identification of the classical nuclear localization signal-like sequences in INM proteins lead to the conclusion that transport receptors for soluble proteins called kap-alpha/beta1 also facilitate the passage of membrane proteins through nuclear pore complexes.
