2 mg every): 20-mer peptides going for walks by the N-terminus of AKAP79 in 5-amino-acid increments, commencing at 21-40 and ending at 116-135 for a whole of 20 peptides and 20-mer peptides corresponding to AKAP79 (77-96) containing possibly WT sequence or the substitutions W79A, L82A, L85A, V86A, L82P. Cells have been transfected with WT, Δ33-48, Δ79-86, or Δ391-400 (‘ΔPKA’) AKAP79.
