front 1 Signal Transduction Pathway | back 1 A series of steps linking a mechanical, chemical, or electrical stimulus to a specific cellular response |
front 2
Local Regulators | back 2 A secreted molecule that influences cells near where it is secreted |
front 3 Hormones | back 3 In multi-cellular organisms, one of many types of secreted chemicals that are formed in specialized cells, travel in body fluids, and act on specific target cells in other parts of the body, changing the target cells' functioning. Hormones are thus important in long-distance signaling |
front 4 1.) Reception | back 4 no data |
front 5 2.) Transduction | back 5 no data |
front 6 3.) Response | back 6 no data |
front 7 Ligand | back 7 A molecule that binds specifically to another molecule, usually a large one |
front 8 G protein-coupled receptor (GPCR) | back 8 no data |
front 9 G Protein | back 9 no data |
front 10 Receptor tyrosine kinases (RTKs) | back 10 A receptor protein spanning the plasma membrane, the cytoplasmic (intracellular) part of which can catalyze the transfer of a phosphate group from ATP to a tryosine on another protein. RTKs often respond to the binding of a signaling molecule by dimerizing and then phosphorylating a tyrosine on the cytoplasmic portion of the other receptor in the dimer. The phosphorylated tyrosines on the receptors then activate other signal transduction proteins within the cell. |
front 11 Ligand-gated ion channel (receptor) | back 11 A transmembrane protein containing a pore that opens or closes as it changes shape in response to signaling |
front 12 Protein kinase | back 12 An enzyme that transfers phosphate groups from ATP to a protein, thus phosphorylating the protein |
front 13 Protein phosphatases | back 13 An enzyme that removes phosphate groups from (dephosphorylates) proteins, often functioning to reverse the effect of a protein kinase |
