What is a receptor protein?
The intracellular proteins form the most important class of receptors called receptor proteins.
Receptor proteins are located in the cytoplasm, cell membrane, or nuclear membrane.
1. Cytoplasmic receptor proteins include those that respond to steroid hormones. Ligand activated receptors may enter the cell nucleus where they modulate gene expression.
2. Receptors within cell membranes may be peripheral or trans-membrane proteins. Many receptors for hormones and neurotransmission are trans-membrane proteins.
- a. Metabotropic receptors are coupled to G-proteins, acting through various secondary pathways involving ion channels, enzymes such as adenylyl (adenylate) cyclases, and phospholipases, or PDZ domains.
- b. Ionotropic receptors are ligand-activated ion channels that permit entry of ions when the central pore is open. A receptor protein is protein molecule that found embedded in the plasma membrane surface of a cell. It receives chemical signals from outside the cell.
receptor protein and marker protein are differente''marker protein have cell surface marker that act as name together, the identification of different types of cells and the receptor proteins transfer information from the outside of the cell to the inside receptor proteins are like boulders that how it's difference.
Some examples of proteins are: 1. structure protein - collagen 2. transport protein - HDNA polymerasesignal protein - EGF 4. motor protein - miosin 5. enzyme - DNA polymerase 6. gene regulatory protein - transcription factor 7. special proposal protein - glue protein 8. storage protein 9. receptor protein - insulin receptor
How does a transmembrane receptor cause the stimulation of a cell does it take something from the chemokine and feed it through its transversile midsection and into the cell giving it to a transport?
Meat, fish and eggs are proteins. some examples are; 1.structure protein - collagen 2.transport protein-HDNA polymerasesignal protein-EGF 4.motor protein-miosin 5.enzyme- DNApolymerase 6.gene regulatory protein-transcription factor 7.special proposal protein-glueprotein 8.storage protein- 9.receptor protein-insulin receptor
some eg. of proteins are 1.structure protein - collagen 2.transport protein-HDNA polymerasesignal protein-EGF 4.motor protein-miosin 5.enzyme- DNApolymerase 6.gene regulatory protein-transcription factor 7.special proposal protein-glueprotein 8.storage protein- 9.receptor protein-insulin receptor e.g. Beans, bread, potatoes :)
Some cell receptor is held with it some proteins that transform the signal when a particular ligand is bind. When a ligand binds to a receptor it results in conformation changes in the receptor. The receptor interact with the other protein attached to it and mediate signal transduction by producing some secondary messengers that's how the signal is amplified and create a respond.... (eg., G -Protein coupled receptor)
What is the process in which a protein binds to a particle and uses energy to move through the cell membrane?
The receptor it self is a trans-membrane protein and doesn't act as an ion channel further more the G-protein involves several functions by its different subunits (G-alph: activation of PLC and adenylcyclase. and G-beta,gamma: activation of potassium channel) and the receptor is coupled with more than one G-protein which lead to amplification of the signal. So G-protein could be possibly evolved to do several functions and amplify them by one receptor
If your protein is fairly low and you work out on a regular basis what changes will you notice once you start taking a protein supplement?
You may be able to build muscle mass quicker, you'll also be able to drop fat quicker. G-proteins are trimeric, found on cytoplasmic side. Note that they are called G-protein coupled receptors (receptor protein that are coupled to G-proteins) receptor proteins vary but GCPR have common G-proteins transducing signal. e.g.: receptor protein could be 7TM for example necessary for growth of muscles
