  2. Insulin signal transduction pathway - Wikipedia

    en.wikipedia.org/wiki/Insulin_signal...

    The influx of Ca 2+ ions causes the secretion of insulin stored in vesicles through the cell membrane. The process of insulin secretion is an example of a trigger mechanism in a signal transduction pathway because insulin is secreted after glucose enters the beta cell and that triggers several other processes in a chain reaction.

  3. Insulin - Wikipedia

    en.wikipedia.org/wiki/Insulin

    The insulin signal transduction pathway begins when insulin binds to the insulin receptor proteins. Once the transduction pathway is completed, the GLUT-4 storage vesicles becomes one with the cellular membrane. As a result, the GLUT-4 protein channels become embedded into the membrane, allowing glucose to be transported into the cell.

  4. Insulin receptor - Wikipedia

    en.wikipedia.org/wiki/Insulin_receptor

    The insulin receptor (IR) is a transmembrane receptor that is activated by insulin, IGF-I, IGF-II and belongs to the large class of receptor tyrosine kinase. [5] Metabolically, the insulin receptor plays a key role in the regulation of glucose homeostasis; a functional process that under degenerate conditions may result in a range of clinical manifestations including diabetes and cancer.

    Insulin resistance, or low insulin sensitivity, happens when cells throughout the body don’t respond properly to the hormone insulin, especially cells in muscles, fat and the liver. Insulin is a ...

  6. Biochemical cascade - Wikipedia

    en.wikipedia.org/wiki/Biochemical_cascade

    Each signal transduction occurs with a primary extracellular messenger that binds to a transmembrane or nuclear receptor, initiating intracellular signals. The complex formed produces or releases second messengers that integrate and adapt the signal, amplifying it, by activating molecular targets, which in turn trigger effectors that will lead ...

  7. Tyrosine kinase - Wikipedia

    en.wikipedia.org/wiki/Tyrosine_kinase

    Insulin receptor substrates are molecules that function in signaling by regulating the effects of insulin. [2] Many receptor enzymes have closely related structure and receptor tyrosine kinase activity, and it has been determined that the foundational or prototypical receptor enzyme is insulin. [ 2 ]

  9. GLUT4 - Wikipedia

    en.wikipedia.org/wiki/GLUT4

    Insulin is stored in beta cells in the pancreas. When glucose in the blood binds to glucose receptors on the beta cell membrane, a signal cascade is initiated inside the cell that results in insulin stored in vesicles in these cells being released into the blood stream. [27] Increased insulin levels cause the uptake of glucose into the cells.
