Despite the fact that G protein-coupled receptors (GPCRs) are largest signal-conveying receptor family and mediate many physiological processes, their role in tumor biology is underappreciated. Numerous lines of evidence now associate GPCRs downstream signaling targets cancer growth development. Indeed, control features tumorigenesis, including immune cell-mediated functions, proliferation, invasion survival at secondary site. Technological advances have further substantiated GPCR modifications human tumors. Among these point mutations, gene overexpression, silencing by promoter methylation number copies. At this point, it imperative to elucidate specific pathways "cancer driver" GPCRs. Emerging data on functional selectivity "biased agonism"; hence, there a diminishing enthusiasm for concept "one drug per target" increasing interest identification several options. Therefore, determining appropriate context-dependent conformation as well contribution alterations development remain significant challenges discovery dominant genes targeted therapeutics.

There are at least two types of cannabinoid receptors (CB1 and CB2). Ligands activating these G protein-coupled (GPCRs) include the phytocannabinoid Δ9-tetrahydrocannabinol, numerous synthetic compounds, endogenous compounds known as endocannabinoids. Cannabinoid receptor antagonists have also been developed. Some ligands activate or block one type more potently than other type. This review summarizes current data indicating extent to which undergo orthosteric allosteric interactions with non-CB1, non-CB2 established GPCRs, deorphanized such GPR55, ligand-gated ion channels, transient potential (TRP) channels peroxisome proliferator-activated nuclear receptors. From data, it is clear that some interact similarly CB1 and/or CB2 likely display significantly different pharmacological profiles.

Lysophosphatidic acid (LPA) is a small, ubiquitous phospholipid that acts as an extracellular signaling molecule by binding to and activating at least five known G protein-coupled receptors (GPCRs): LPA(1)-LPA(5). They are encoded distinct genes named LPAR1-LPAR5 in humans Lpar1-Lpar5 mice. The biological roles of LPA diverse include developmental, physiological, pathophysiological effects. This diversity mediated broad overlapping expression patterns multiple downstream pathways activated cognate receptors.

Cannabinoids have numerous physiological effects. In the years since molecular identification of G protein-coupled receptors CB1 and CB2, ion channel TRPV1, their corresponding endogenous ligand systems, many cannabinoid-evoked actions been shown conclusively to be mediated by one these specific receptor targets. However, there remain several examples where classical cannabinoid do not explain observed pharmacology. Studies using mice genetically deleted for known confirmed existence additional targets, which come collectively as non-CB1/CB2 receptors. Despite intense research efforts, identity remains most part unclear.
