QuestionAnswer
release mechanism for steroid hormones
Ligand binding activates a G-protein (GTP-binding protein). Activated G-protein stimulates (or inhibits) an effector
this type of receptor protein is a channel for ion transport
this term describes steps that “transduce” signal binding to receptor into cellular response(s)
true or false: intracellular receptors regulate transcription.
thyroid hormones bind which type of receptor? (cell surface or intracellular)
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)
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
this protein activates G proteins by exchanging GDP for GTP
these enzymes remove phosphate groups added by kinases
peptide or protein hormones bind which type of receptor? (cell surface or intracellular)
this protein inactivates G protein
PKA catalytic subunits phosphorylate what?
release mechanism for protein or peptide hormones
release mechanism for thyroid hormones
QuestionAnswer
G proteins are active when what molecule is bound?
Active RTK phosphorylates ______ residues
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
enzyme that phosphorylates protein target
catecholamine hormones bind which type of receptor? (cell surface or intracellular)
CRE stands for what?
release mechanism for catecholamine hormones
which subunit of the G-protein binds GTP and GDP?
term for signal that stably occupies a receptor
term for molecules that mimics signal of ligand (e.g., drug)
hydrophobic molecules generally bind to _____ receptors.
steroid hormones bind which type of receptor? (cell surface or intracellular)
these receptors bind to signaling molecules that diffuse into the cell
Phosphotyrosines recruit which adaptor protein
cAMP is synthesized by what?
