G-protein-coupled receptors (GPCRs) relay numerous extracellular signals by triggering intracellular signaling through coupling with G proteins and arrestins. Recent breakthroughs in the structural determination of GPCRs and GPCR-transducer complexes represent important steps toward deciphering GPCR signal transduction at a molecular level.

Regulation of GPCR Signaling It is well known that GPCR signaling is regulated by the phosphorylation status of the receptor. The question we have asked is whether the precise sites on the receptor that are phosphorylated is dependent on the cell type in which the receptor is expressed.

G Protein coupled Receptors Signaling Background G Protein Coupled Receptors (GPCRs) regulate a wide variety of normal biological processes and play a role in the pathophysiology of many diseases upon dysregulation of their downstream signaling activities.

Recent breakthroughs in the structural determination of GPCRs and GPCR-transducer complexes represent important steps toward deciphering GPCR signal transduction at a molecular level. GPCRs comprise a single polypeptide that is folded into a spherical shape and retained in the plasma membrane. They are activated through extracellular signals in the form of mediators or ligands. Such signals inform cells about the life-sustaining nutrients present or absent in the cell environment. The binding of a signal molecule by the extracellular part of the G-protein linked receptor causes the cytosolic tail of the receptor to interact with, and alter the conformation of, a G-protein. This has two consequences: First, the alpha subunit of the G- protein loses its GDP and binds a GTP instead.

Select GPCRs exhibit classical signaling, that is restricted to cell membranes, as well as newly described persistent signaling that depends on internalization of the GPCR bound to β-arrestins. Termination of non-canonical endosomal signaling requires intraluminal acidification and sophisticated protein trafficking machineries.

The extracellular loops contain two highly-conserved cysteine residues that form disulphide bonds to stabilize the structure of the receptor. Functional Diversity of GPCRs • Signaling molecules can cause a focused response in one cell and plethora of different responses in another; single receptor can activate several pathways in a given cell, though the predominant pathway may vary from cell to cell. The GPCR cycle, described in more detail below, is an elegant cellular solution for sensing a specific exogenous signal, transducing it to a signaling cascade, and then terminating the signal. GPCRs are widely represented in most life forms, from bacteria to fungi and animals, including all of the major model organisms.

Dysregulation of GPCR signaling underlines numerous skin inflammatory diseases and cancer, with smoothened‐driven basal cell carcinoma being a main example of a GPCR‐associated cancer. In this review, we discuss the impact of GPCRs and their signaling partners in skin keratinocyte biology, particularly in the regulation of the epidermal stem cell compartment.

GPCRs are widely represented in most life forms, from bacteria to fungi and animals, including all of the major model organisms. G Protein coupled Receptors Signaling Background G Protein Coupled Receptors (GPCRs) regulate a wide variety of normal biological processes and play a role in the pathophysiology of many diseases upon dysregulation of their downstream signaling activities. GPCR Signaling GPCRs, as their name implies, interact with G proteins in the plasma membrane. The signaling cascades of a GPCR initiate from the binding of an external signaling molecule in the form of a ligand or other signal mediator. G-protein coupled receptors (GPCRs) G protein–coupled receptors (GPCRs) are receptors that are closely related with a member of the guanosine nucleotide–binding protein (G protein) family.
