Receptor/Tyrosine Kinases and Ligand-Gated Ion Channels

receptor/tyrosine kinases are a specific type of ______________ pathway

protein-based hormone

receptor

part of protein that sticks out of the cell

tyrosine kinase enzyme

part of protein that extends into the cytoplasm

kinase enzyme

transfers a phosphate group (usually from ATP) to another molecule (in this case, tyrosine)

dimer

chemical compound composed of two identical or similar subunits or monomers

tyrosine kinases involved in ___________________

regulating cell division

tyrosine kinases are a promising target for ___________________

cell-specific anti-cancer drugs

how can the same signaling molecule have different effects on different cells?

1. different receptor

2. different relay proteins in cytoplasm get activated

sympathetic nervous system

responsible for “fight or flight”

ligand-gated ion channels are important because

they allow for your neurons to successfully transmit signals, since they are part of the process
