Structure of the insulin receptor-insulin complex by single-particle cryo-EM analysis. [PDF]
The insulin receptor is a dimeric protein that has a crucial role in controlling glucose homeostasis, regulating lipid, protein and carbohydrate metabolism, and modulating brain neurotransmitter levels.

Insulin Receptor Isoforms and Insulin Receptor/Insulin-Like Growth Factor Receptor Hybrids in Physiology and Disease [PDF]
In mammals, the insulin receptor (IR) gene has acquired an additional exon, exon 11. This exon may be skipped in a developmental and tissue-specific manner. The IR, therefore, occurs in two isoforms (exon 11 minus IR-A and exon 11 plus IR-B). The most relevant functional difference between these two isoforms is the high affinity of IR-A for IGF-II.

Interaction of Insulin Receptor Substrate 3 with Insulin Receptor, Insulin Receptor-related Receptor, Insulin-like Growth Factor-1 Receptor, and Downstream Signaling Proteins [PDF]
Insulin receptor substrates (IRS) mediate biological actions of insulin, growth factors, and cytokines. All four mammalian IRS proteins contain pleckstrin homology (PH) and phosphotyrosine binding (PTB) domains at their N termini. However, the molecules diverge in their C-terminal sequences.

Insulin receptor trafficking steers insulin action
In this issue, Boothe and colleagues analyze insulin receptor trafficking in pancreatic beta cells to unravel the trafficking route of insulin receptors and provide novel insights into the potentially different roles of insulin receptor splice variants [1].

Rapid insulin-dependent endocytosis of the insulin receptor by caveolae in primary adipocytes. [PDF]
BACKGROUND:The insulin receptor is localized in caveolae and is dependent on caveolae or cholesterol for signaling in adipocytes. When stimulated with insulin, the receptor is internalized.

Insulin-Responsive Transcription Factors
The hormone insulin executes its function via binding and activating of the insulin receptor, a receptor tyrosine kinase that is mainly expressed in skeletal muscle, adipocytes, liver, pancreatic β-cells, and in some areas of the central nervous system ...

Systematic evaluation of the metabolic to mitogenic potency ratio for B10-substituted insulin analogues. [PDF]
BACKGROUND: Insulin analogues comprising acidic amino acid substitutions at position B10 have previously been shown to display increased mitogenic potencies compared to human insulin and the underlying molecular mechanisms have been subject to much ...

Insulin sensitizes neural and vascular TRPV1 receptors in the trigeminovascular system
Background Clinical observations suggest that hyperinsulinemia and insulin resistance can be associated with migraine headache. In the present study we examined the effect of insulin on transient receptor potential vanilloid 1 (TRPV1) receptor-dependent ...
