1.
Nakagawa S, Tager H, Steiner D
Biochemistry . 2000 Dec; 39(51):15826-35. PMID: 11123908
An invariant residue, valine B12, is part of the insulin B-chain central alpha-helix (B9-B19), and its aliphatic side chain lies at the surface of the hydrophobic core of the insulin...

Pittman 4th I, Nakagawa S, Tager H, Steiner D
Biochemistry . 1997 Mar; 36(12):3430-7. PMID: 9131992
[GlyB24]insulin is a novel insulin analog which maintains nearly full biological activity [Mirmira, R. G., & Tager, H. S. (1989) J. Biol. Chem. 264, 6349-6354] even though its structure, as...

Pittman 4th I, Tager H
Biochemistry . 1995 Aug; 34(33):10578-90. PMID: 7654714
A conformational change, termed the T --> R transition, which can be detected by visible, circular dichoric, and fluorescence spectroscopy, occurs in native insulin and tryptophan substituted insulin analogs ([TrpB25]-,...

Zhong P, Cara J, Tager H
Proc Natl Acad Sci U S A . 1993 Dec; 90(24):11451-5. PMID: 8265572
We have investigated by use of placental membranes the mechanisms through which insulin-like growth factor I (IGF-I) comes to be associated with its alpha 2 beta 2 receptor heterotetramer. Our...

Nakagawa S, Johansen N, Madsen K, Schwartz T, Tager H
Int J Pept Protein Res . 1993 Dec; 42(6):578-84. PMID: 8307689
To evaluate more thoroughly the importance of main-chain structure and flexibility in ligand interactions with the insulin receptor, we undertook to synthesize analogues with reduced peptide bonds in the COOH-terminal...
6.
Nakagawa S, Tager H
Biochemistry . 1993 Jul; 32(28):7237-43. PMID: 8343513
We have investigated the effects of altering the disposition between the COOH-terminal B chain domain of insulin and the core of the insulin molecule on ligand interactions with the hepatocyte...
7.
Post S, Rubinstein P, Tager H
Proc Natl Acad Sci U S A . 1993 Mar; 90(5):1662-6. PMID: 8383321
We have investigated the mechanisms through which des-His1-[Glu9]glucagon amide functions as a peptide antagonist of the glucagon receptor/adenylyl cyclase system. Studies with radiolabeled peptides identified that (i) the antagonist bound...

Schaffer L, Kjeldsen T, Andersen A, Wiberg F, Larsen U, Cara J, et al.
J Biol Chem . 1993 Feb; 268(5):3044-7. PMID: 8428981
We have examined, by use of a hybrid insulin/insulin-like growth factor-I analog and chimeric insulin/type I insulin-like growth factor receptors, the interplay between ligand and receptor structure in determining the...

Post S, Miyazaki H, Tager H
J Biol Chem . 1992 Dec; 267(36):25776-85. PMID: 1334486
We have investigated (by use of intact and saponinpermeabilized canine hepatocytes) the roles of Mg2+ and guanyl nucleotides in regulating glucagon-receptor interactions. In contrast to intact cells, saponinpermeabilized hepatocytes bind...

Nakagawa S, Tager H
Biochemistry . 1992 Mar; 31(12):3204-14. PMID: 1554705
In order to evaluate the cause of the greatly decreased receptor-binding potency of the naturally occurring mutant human insulin Insulin Wakayama ([LeuA3]insulin, 0.2% relative potency), we examined (by the semisynthesis...
