Patent ID: 8491914

Claim:
A complex comprising: a) an antibody or antigen-binding fragment thereof attached to one or more anchoring domain (AD) moieties from an AKAP protein or to one or more dimerization and docking domain (DDD) moieties from human protein kinase A (PKA) regulatory subunit RIα, RIβ, RIIα or RIIβ; and b) one or more siRNA carrier moieties wherein the carrier moiety is a protamine, each siRNA carrier attached to a DDD moiety from human PKA regulatory subunit RIα, RIβ, RIIα, or RIIβ or to an AD moiety from an AKAP protein and one or more siRNA attached to the one or more siRNA carrier moieties; wherein two copies of the DDD moiety form a dimer and bind to the AD moiety to form the complex and wherein when the antibody or fragment is attached to one or more AD moieties, the siRNA carrier is attached to a DDD moiety, or when the antibody or fragment is attached to one or more DDD moieties, the siRNA carrier is attached to an AD moiety and wherein the antibody is selected from the group consisting of hA19, hA20, hLL1, hLL2, hL243, hMN-14, hMN-15, hR1, hRS7 and hPAM4.
