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