Protein tyrosine kinase-mediated pathways in G protein-coupled receptor signaling

Cell Biochemistry and Biophysics Aims and scope Submit manuscript

Abstract

Abundant evidence has indicated that protein tyrosine kinases (PTKs) convey signals from G protein-coupled receptors (GPCRs) to regulate cell proliferation, migration, adhesion, and potentialy cellular transformation. Molecular mechanisms by which PTKs regulate such diverse effects in GPCR signaling are not well understood. Recently, an unifying theme has emerged where both growth factors and GPCRs utilize protein tyrosine kinase activity and the highly conserved Ras/MAP kinase pathway to control mitogenic signals. Additionally, PTKs are also involved in the regulation of signal transmission from GPCRs to activation of the JNK/SAPK kinase pathway. Furthermore novel insights in chemokine receptor-activated PTKs and their role in mediating cell functions are discussed in this review.
