The gateway for molecular trafficking between the cytoplasm and the nucleus is the Nuclear Pore Complex (NPC). Through mass spectral analysis of the isolated Nuclear Pore Nup107-160 subcomplex, we discovered an in vivo interaction with Werner's Helicase Interacting Protein 1, (WRNIP1 or WHIP). WHIP was originally identified as a binding partner of Werner protein (WRN), which functions to maintain genome stability and is responsible for the progeria disease, Werner syndrome. We established the reciprocal isolation of Nup107 by alpha-WHIP. WHIP was found in purified Nuclear Envelope (NE) fractions treated with DNase/RNase/Heparin. We demonstrated by immunofluorescence microscopy that WHIP is located at the nuclear rim as well as punctate regions in the nuclear matrix. Ultimately, synchronized cells show a dynamic association between WHIP and the Nup107-160 subcomplex through the cell cycle without an interaction with WRN. We thus identify WHIP as a partner/component of the NE/NPC and set forth to investigate a role for the protein positioned at the NPC.
