How does RSTK signal transduction differ from RTK and GPCR signaling? (Drawing a table may help)

Answer 1

Answer #1

Receptor Serine/Threonine Kinases	Receptor Tyrosine Kinases	G-Protein-Coupled Receptors
Receptor serine/threonine receptors transduce signals for the TGF-beta family	IT is a cell surface receptor that binds and respond to growth factors such as fibroblast growth factors (FGF)	It interacts with G proteins in the plasma membrane.
They perform inhibitory as well as stimulatory signal action for growth and differentiation by binding to members of the transforming growth factor‐β (TGF‐β) superfamily.	Binding of a signaling molecule with an RTK activates tyrosine kinase in the cytoplasmic tail of the receptor which then launches a series of enzymatic reactions that carry the signal to the nucleus.	Binding of a signaling molecule to a GPCR results in G protein activation, which in turn triggers the production of any number of second messengers.
Transduce signals by means of serine/threonine.	Transduce signals by means of tyrosine kinase activity.	GPCRs transduce signals by means of heterotrimeric G proteins.
