Patent ID: 8299213

Claim:
A peptide, which specifically binds a type 2A protein phosphatase holoenzyme or one of its subunits in vitro, which is a fragment of the CK2α protein, and which consists of a sequence selected from the group consisting of: IKILKPVKKKKI; (SEQ ID No: 17) ILKPVKKKKIKR; (SEQ ID No: 18) KPVKKKKIKREI; (SEQ ID No: 19) VKKKKIKREIKI; (SEQ ID No: 20) KKKIKREIKILQ; (SEQ ID No: 21) KIKREIKILQNL; (SEQ ID No: 22) and an isolated peptide which differs from SEQ ID NOS: 17-22 only by substitution or deletion of one or more amino acids, wherein the isolated peptide consists of a sequence having 80% or higher homology to any peptide of SEQ ID NOS: 17-22, and wherein the isolated peptide conserves the property of binding to the type 2A protein phosphatase holoenzyme or one of its subunits in vitro.
