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