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