QuestionAnswer
this type of receptor protein is a channel for ion transport
which subunit of the G-protein binds GTP and GDP?
cAMP is synthesized by what?
hydrophilic molecules generally bind to _____ receptors.
these receptors transduce signals across the plasma membrane via changes in receptor protein conformation that lead to changes in receptor protein activity and/or receptor protein
G proteins are active when what molecule is bound?
release mechanism for protein or peptide hormones
this protein activates G proteins by exchanging GDP for GTP
Ligand binding activates a G-protein (GTP-binding protein). Activated G-protein stimulates (or inhibits) an effector
PKA catalytic subunits phosphorylate what?
release mechanism for catecholamine hormones
hydrophobic molecules generally bind to _____ receptors.
cAMP binds the ______ subunit of protein kinase A (PKA)
release mechanism for thyroid hormones
these receptors bind to signaling molecules that diffuse into the cell
Active RTK phosphorylates ______ residues
peptide or protein hormones bind which type of receptor? (cell surface or intracellular)
QuestionAnswer
catecholamine hormones bind which type of receptor? (cell surface or intracellular)
term for signal that stably occupies a receptor
this protein inactivates G protein
these enzymes remove phosphate groups added by kinases
this term describes steps that “transduce” signal binding to receptor into cellular response(s)
release mechanism for steroid hormones
Cytosolic domain of this receptor either has intrinsic enzymatic activity or activates an associated enzyme. There is no enzyme activity without ligand.
true or false: intracellular receptors regulate transcription.
enzyme that phosphorylates protein target
these receptors bind to signaling molecules that do not diffuse into cell
CRE stands for what?
term for molecules that mimics signal of ligand (e.g., drug)
thyroid hormones bind which type of receptor? (cell surface or intracellular)
steroid hormones bind which type of receptor? (cell surface or intracellular)
Phosphotyrosines recruit which adaptor protein
these proteins have multiple protein binding domains and can form multi-protein complexes for signal transduction
