Figure 1. CGN is an AMIS-associated FIP5-binding protein.
(a) Schematic model showing the formation of a nascent apical lumen. Rab11/FIP5 endosomes are transported along central spindle microtubules and fuse to the AMIS present at the midbody during late telophase. (b) List of proteins identified in FIP5 immunoprecipitate by mass spectroscopy analysis. Proteins known to be present in the same complex are highlighted together. (c) FIP5 co-immunoprecipitation with GFP-CGN from MDCK lysates. Images shown are the immunoblots after probing with anti-CGN (top gel) or anti-FIP5 (bottom gel) antibodies. (d) Co-immunoprecipitation of purified 6His-CGN with 6His-FIP5. Images shown are the immunoblots after probing with anti-CGN (top gel) or anti-FIP5 (bottom gel) antibodies. (e) Mapping 6His-FIP5 binding domain using glutathione bead pull-down assays. Image shown is Coomassie stained SDS–PAGE gel.
