Exam 1 Flashcards
Intracellular receptors
Have steroid, hormones, and structural relatives
Steroid, hormones, and structural relatives
– Consist of cholesterol, testosterone, estradiol, cortisol, vitamin D, retinol acid
– Hormones go through p.m.
– Binds to receptor protein inside of plasm
– Receptor enters, nucleus, function, transcription factor
Receptor binding DNA to regulate expression
Nitric oxide
– Nitric oxide released from cell
– Goes through plasma membrane into another cell
– Find receptor protein, cytoplasm, receptor
– guanylyl cyclase
– Signal binds, and enzymes are active
What is nitroglycerin?
A drug to help relaxation during heart attacks it increases your nitric oxide
What is Viagra?
Viagra make sure you maintain the level of cyclic GMP
What are neurotransmitters
Nerve cells like peregrine. Consist of adrenaline dopamine serotonin, and a morphine, small and hydrophilic typically binds to a lion gated. I am on channel or to a receptor called G protein cup receptor.
What are proteins in poly peptides?
They Varian size and typically are hydrophilic their growth factor proteins, and cytokines
What are Eicosanoids
Hydrophobic lipids, too big to pass through the plasma membrane. They control blood vessel, dilation, and construction inflammation also.
What is the procedure for ligand gated on channels?
– Ion gated channels start off, closed
– A lines to the outside of the channel, causing it to open
– When it opens ions go through into the cytoplasm of the cell
What is the procedure for G protein coupled receptor?
– A signal binds to the terminal of the cell
– See terminal changes confirmation
– GDP is removed by using GEF and replaced with GPTP on Alpha
Alpha GTP is active and removed from beta and gamma
– Beta and gamma are active as well and downstream effects
How do you enact or turn off a G protein cup receptor?
You’re remove the phosphate and it will replace GTP with GDP again
Process of RTK dimerization auto phosphorylation
– Extra cellular is the receptor, while intracellular is the enzyme
– Start with signal, dimer growth, factor
– You get ligand induced receptor, dimerization
– Kindness domain is active and will fast forward tire, roasted of other receptors– Chinese domain is active and phosphate tyrosines of other receptors
-you will get auto or cross for elation which will increase activity
