Abstract
G protein-coupled receptors are known for their ability to generate a wide range of functional responses through interaction with various intracellular partners. This versatility is particularly evident within the chemokine receptor family, where conventional receptors signal primarily through classic G protein-coupled pathways while atypical chemokine receptors appear not to possess such ability but instead couple to alternative intracellular partners such as β-arrestins. Functional diversity in signaling presents unique opportunities for drug development, allowing different pathways to be selectively targeted to meet specific therapeutic needs. This minireview explores the mechanisms by which G protein-coupled receptor signaling, particularly within the chemokine receptor family, can be diversified at the modulatory, transmembrane, and intracellular levels.
