The protein kinase A-anchoring proteins (AKAPs) are defined by their ability to scaffold protein kinase A to specific subcellular compartments. Each of the AKAP family members utilizes unique targeting domains specific for a particular subcellular compartment. AKAP350 is a multiply spliced AKAP family member localized to the centrosome and the Golgi apparatus. Three splicing events in the carboxyl terminus of AKAP350 generate the AKAP350A, AKAP350B, and AKAP350C proteins. A monoclonal antibody recognizing all three splice variants as well as a polyclonal antibody specific for AKAP350A demonstrated both centrosomal and Golgi apparatus staining in paraformaldehyde-fixed HCA-7 cells. Golgi apparatus-associated AKAP350A staining was dispersed following brefeldin A treatment. Using GFP chimeric constructs of the carboxyl-terminal regions of AKAP350A, a Golgi apparatus targeting domain was identified between amino acids 3259 and 3307 of AKAP350A. This domain was functionally distinguishable from the recently described centrosomal targeting domain (PACT domain, amino acids 3308-3324) located adjacent to the Golgi targeting domain. These data definitively establish the specific association of AKAP350A with the Golgi apparatus in HCA-7 cells.
