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