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