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