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