Abstract An analogue of insulin in which the naturally occurring tyrosine residue in position B16 is replaced by a glutamine residue has been synthesized. Glutamine appears in the corresponding position in the B-domain of the insulin-like growth factors. This analogue displays 9% of the potency of insulin in binding to the insulin receptor from rat liver plasma membranes, 17% in stimulating the conversion of [3-3H] glucose into lipids in rat adipocytes, and 23% in insulin radioimmunoassay, but 40% of the potency of insulin in stimulating DNA synthesis in cultured chick fibroblasts. The analogue is a more potent mitogen than is a hybrid molecule which contains the A-chain of insulin and the entire B-domain sequence of IGF-I.
