RESUMO
The synthetic peptide Ac-WFVGLKKNGSSKRGPRT-NH2,related to the human FGF-1 sequence, was shown to be mitogenic upon Balb/c 3T3 fibroblasts in culture (ED50=10-20 muM) and to compete with the growth factor for cellular binding (ID50 = 30-50 muM). The results described suggest that the mitogenic activity of the peptide is dependent on the presence of the residues 122-127 (WFVGLK) in its structure. Also, its affinity for the cellular receptors seems to be dependent on the presence of residues that are important for FGF-heparin binding such as K127, K133 and R137.
