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