Term
lipophilic cell surface receptor
Definition
Fever/pain/adrenaline
fast response
FAP
Term
Hydrophilic that interact with cell surface receptor
Definition
Don't cross membrane. Large. Peptide
Glucagon, insulin, GH
PIGG
Term
Small lipophilic
Definition
Diffuse. Steroids. adreocortical. gonad. thyroid.
TGADS
Term
G Protein
Definition
Ligand binds receptor. Activates GTP. Alpha subunit disocaites BY. Alpha activates adenyl cyclase. This activates kinases / camp.
Term
G Protein
Definition
Ligand binds receptor. Activates GTP. Alpha subunit disocaites BY. Alpha activates adenyl cyclase. This activates kinases / camp.
Term
Ion Channel Receptor
Definition
Ligand binding changes conformation allowing ion flow.
eX: neural transmitters. (acetycholine)
Term
Tyrosine Kinase Binding Receptor.
Definition
Hormones bind 2 external receptor. THis activates auto-phosphorylation. This pi activates other messengers and this process cascades down. CH2->RAS(gtp)->RAF->MAPK->transcription
Term
Receptors with intrinsic enzymatic activity
Definition
Insulin induced tyrosine. phosphatases.

1 receptor with many functions. Cascades
Term
Ras turned on by _
Definition
GTP
Term
Two types of protein kinase
Definition
Tyrosine/Serine
Term

PTB binds N terminal. (TRK n terminal is extracellular)
SH2 BIND c terminal.
Definition
N terminal has targeting region
Term
Death Ligans
Definition
Fasl TNF
