|3. (WO2007016763) PEPTIDES TARGETED TO PROTEIN KINASE C ISOFORMS AND USES THEREOF|
|Title:||PEPTIDES TARGETED TO PROTEIN KINASE C ISOFORMS AND USES THEREOF|
Peptides having a sequence of general formula (I), or the retro form thereof, and having an affinity for one or more mammalian protein kinase C-alpha isoforms are provided: X-[(HY-HB)n-linker]m-(HB-HY)2-HB-(HY)m-Z (I) wherein: HY represents a block of 1 to 4 hydrophobic amino acid residues selected from the group of: Ala, GIy, He, Leu, Phe and VaI; HB represents a block of 1 to 4 amino acid residues capable of forming hydrogen bonds selected from the group of: Arg, Asn, Asp, GIu, GIn, Lys and Ser; 'linker' represents 1 to 4 Gly residues; n is 1, 2 or 3; m is 0 or 1; X represents the N-terminus of the peptide or a modified version thereof, and Z represents the C-terminus of the peptide or a modified version thereof. The peptides can be used as probes, screening agents, targeting agents, purification agents and diagnostic agents.
