QuestionAnswer
cAMP binds the ______ subunit of protein kinase A (PKA)
peptide or protein 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
this protein inactivates G protein
true or false: intracellular receptors regulate transcription.
enzyme that phosphorylates protein target
these receptors bind to signaling molecules that do not diffuse into cell
this protein activates G proteins by exchanging GDP for GTP
these enzymes remove phosphate groups added by kinases
term for molecules that mimics signal of ligand (e.g., drug)
this type of receptor protein is a channel for ion transport
release mechanism for protein or peptide hormones
which subunit of the G-protein binds GTP and GDP?
hydrophobic molecules generally bind to _____ receptors.
hydrophilic 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.
Active RTK phosphorylates ______ residues
QuestionAnswer
release mechanism for catecholamine hormones
steroid hormones bind which type of receptor? (cell surface or intracellular)
release mechanism for steroid hormones
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
G proteins are active when what molecule is bound?
PKA catalytic subunits phosphorylate what?
these receptors bind to signaling molecules that diffuse into the cell
catecholamine hormones bind which type of receptor? (cell surface or intracellular)
this term describes steps that “transduce” signal binding to receptor into cellular response(s)
CRE stands for what?
cAMP is synthesized by what?
release mechanism for thyroid hormones
term for signal that stably occupies a receptor
Ligand binding activates a G-protein (GTP-binding protein). Activated G-protein stimulates (or inhibits) an effector
thyroid hormones bind which type of receptor? (cell surface or intracellular)
