BIOL 1010U Lecture Notes - Lecture 12: Steroid Hormone Receptor, Guanine, Growth Factor
Document Summary
Q: notch and delta are both transmembrane proteins involved in cell communication in the developing nervous system of vertebrate animals. A: notch is a receptor and delta is a signalling molecule. All cells process information form the environment. Communication most often via chemical signals that bind to specific receptors: hormones, neurotransmitters, co2, h2o. Signals can come from outside the organism, or from neighbouring cells; short distances or long. Examples of molecules that act as signals : plants, ethylene (ripening agent, animals, epinephrine (breakdown of glycogen, increases heart rate and. Receptor: a protein that receives and interprets information carried by signalling molecules (ligand) Ligand binds to a ligand-binding site on receptor conformational shape change in the entire receptor. Receptors can be found on: inside the cell = intracellular receptors, cell surface = cell surface receptors. Receptor and ligand (if steroid: steroid receptor complex, either in cytoplasm or nucleus.
