  • Community guidelines for GPCR ligand bias: IUPHAR review 32

    August 2022 "GPCRs modulate a plethora of physiological processes and mediate the effects of one-third Depending on which ligand activates a receptor, it can engage different intracellular transducers.

    forming a vicious cycle with IGF1/IGF1R signaling pathway "There is a potential correlation between G-protein-coupled receptor-associated sorting protein 1 (GASP1) and breast tumorigenesis. Mechanistically, GASP1 inhibited proteasomal degradation of insulin-like growth factor 1 receptor (IGF1R ) by competitively binding to IGF1R with ubiquitin E3 ligase MDM2, thereby activating its downstream IGF1, in turn, stimulated GASP1 expression by activating the PI3K/AKT pathway, forming a vicious cycle
