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