WebDec 13, 2024 · Mutations in the androgen receptor (AR) ligand-binding domain (LBD) can cause resistance to drugs used to treat prostate cancer. Commonly found mutations include L702H, W742C, H875Y, F877L and T878A, while the F877L mutation can convert second-generation antagonists such as enzalutamide and apalutamide into agonists. WebThe ligand binding causes the conformational changes of receptor and ion channel forming. The binding of Ach to each of four subunits of AchR induces change in receptor and opening the sodium selective channel through the centre of the receptor protein. It causes the depolarisation of surrounding membrane.

WebBinding of a ligand to its receptor is a reversible process, as the ligand will ultimately dissociate from the receptor and may be degraded. Acetylcholine is a good example of a signal regulated in this way; it is degraded by the enzyme cholinesterase within milliseconds of its release from neuron terminals. WebBinding of a ligand to a receptor changes its shape or activity, allowing it to transmit a signal or directly produce a change inside of the cell In this section, we’ll look at different types of receptors and ligands, seeing how they interact to turn information from outside … Generalized diagram of receptor-ligand binding, intracellular signal transduction, … Together, Raf, MEK, and the ERKs make up a three-tiered kinase signaling … But essentially what's happening is a hormone is binding to a receptor on a … So this is a process that we call signal transduction.
