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