WebThe ERBB receptors are a group of receptor tyrosine kinases (RTKs) involved in key cellular functions, including cell growth and survival. They signal through phosphorylated tyrosines on... WebTyrosine Phosphotyrosine When a growth factor binds to the extracellular domain of a RTK, its dimerization is triggered with other adjacent RTKs. Dimerization leads to a rapid activation of the protein's cytoplasmic kinase domains, the first substrate for these domains being the receptor itself.
