Immunoglobulin heavy chain-binding protein binds to misfolded mutant insulin receptors with mutations in the extracellular domain

Autor: Simeon I. Taylor, Hiroko Kadowaki, Tadashi Kadowaki, L Mosthaf, A Ullrich, Domenico Accili

Publikováno v: Journal of Biological Chemistry. 267:586-590

Cell-surface proteins are transported through the endoplasmic reticulum and Golgi apparatus en route to the plasma membrane. Previously, we have identified three point mutations in the insulin receptor gene that impair transport of the mutant recepto

A mutation in the extracellular domain of the insulin receptor impairs the ability of insulin to stimulate receptor autophosphorylation

Autor: Simeon I. Taylor, A Ullrich, L Mosthaf, Domenico Accili

Publikováno v: Journal of Biological Chemistry. 266:434-439

Mutations of the insulin receptor gene have been shown to cause insulin-resistant diabetes in patients with genetic forms of insulin resistance. We have previously reported that a mutation substituting valine for Phe382 in the alpha-subunit of the in

Cellular mechanism of nutritionally induced insulin resistance in Psammomys obesus: overexpression of protein kinase Cepsilon in skeletal muscle precedes the onset of hyperinsulinemia and hyperglycemia

Autor: Y, Ikeda, G S, Olsen, E, Ziv, L L, Hansen, A K, Busch, B F, Hansen, E, Shafrir, L, Mosthaf-Seedorf

Publikováno v: Diabetes. 50(3)

The sand rat (Psammomys obesus) is an animal model of nutritionally induced diabetes. We report here that several protein kinase C (PKC) isoforms (alpha, epsilon, and zeta, representing all three subclasses of PKC) are overexpressed in the skeletal m

Insulin signaling is inhibited by micromolar concentrations of H(2)O(2). Evidence for a role of H(2)O(2) in tumor necrosis factor alpha-mediated insulin resistance

Autor: L L, Hansen, Y, Ikeda, G S, Olsen, A K, Busch, L, Mosthaf

Publikováno v: The Journal of biological chemistry. 274(35)

Both hyperglycemia and tumor necrosis factor alpha (TNFalpha) were found to induce insulin resistance at the level of the insulin receptor (IR). How this effect is mediated is, however, not understood. We investigated whether oxidative stress and pro

Glucose-induced translocation of protein kinase C isoforms in rat-1 fibroblasts is paralleled by inhibition of the insulin receptor tyrosine kinase

Autor: L, Berti, L, Mosthaf, G, Kroder, M, Kellerer, S, Tippmer, J, Mushack, E, Seffer, K, Seedorf, H, Häring

Publikováno v: The Journal of biological chemistry. 269(5)

Rat-1 fibroblasts stably overexpressing high levels of human insulin receptor were used as a model system to study the effects of hyperglycemia on insulin receptor tyrosine kinase (IRK) activity and protein kinase C (PKC) translocation in parallel in

Inositol phospho-oligosaccharides from rat fibroblasts and adipocytes stimulate 3-O-methylglucose transport

Autor: Axel Ullrich, Monika Kellerer, L Mosthaf, F Machicao, Hans-Ulrich Häring, J. Mushack, E Seffer, Lucia Berti, B Sixt

Publikováno v: The Biochemical journal. 295

Inositol phospho-oligosaccharides (IPOs), which are released from liver membranes upon stimulation by insulin, mimic a wide spectrum of insulin effects in different cells, but not the stimulation of glucose transport. We investigated whether other in

Altered pattern of insulin receptor isotypes in skeletal muscle membranes of type 2 (non-insulin-dependent) diabetic subjects

Autor: Monika Kellerer, L Mosthaf, B. Obermaier-Kusser, Giorgio Sesti, E. Seffer, HU Häring, D. E. Pongratz

Publikováno v: Diabetologia. 36(7)

The human insulin receptor exists in two isoforms (HIR-A alpha-subunit 719 amino acids and HIR-B alpha-subunit 731 amino acids) which are generated by alternative splicing of a small exon and display distinct patterns of tissue-specific expression. U
