Intermolecular association of BANK1 isoforms.
(A) Protein extract of cells co-transfected with the BANK1 isoforms tagged either with FLAG-epitope at the N-term (labeled as f) or V5-epitope at the C-term (labeled as v) and probed with anti-V5 antibody.
(B) The same extracts were probed with anti-FLAG antibody.
(C) The co-immunoprecitation of different isoforms labeled differently either with FLAG-epitope or with V5-epitope indicates inter-molecular association, or dimer formation between BANK1 proteins.
