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