[Specific interaction of liposomes coated by insulin synthetic fragments with PC 12 cells].
The synthesized peptides represent the functionally important site for binding to insulin receptor. Amino acids of peptide I correlate with B-chain of insulin at the position B19-B26 and A-chain at the position A20-A21. Amino acids of peptide II correlate with B-chain of insulin at position B23-B26 and A-chain at the position A20-A21. It was shown, that the these peptides increased liposomal binding followed by receptor-mediated endocytosis by cells PC12.
