The invention relates to kinase ligands and polyligands. In particular, the invention relates to ligands, homopolyligands, and heteropolyligands that modulate protein kinase D (PKD) activity. The ligands and polyligands are utilized as research tools or as therapeutics. The invention includes linkage of the ligands and polyligands to cellular localization signals, epitope tags and/or reporters. The invention also includes polynucleotides encoding the ligands and polyligands.
