September 2022 "G-protein-coupled receptors (GPCRs) are involved in a wide array of physiological and Here, we find that protease-activated receptor 4 (PAR4) unexpectedly acts as a potent oncogene, inducing β-catenin stability and transcriptional activity. β-catenin stability and transcriptional activity. following PAR4 activation, in contrast to wt β-catenin.

October 2022 "Protease activated receptors (PARs) are among the first receptors shown to transactivate other receptors: noticeably, these interactions are not limited to members of the same family, but involve receptors as diverse as receptor kinases, prostanoid receptors, purinergic receptors and ionic channels In this review, we will focus on the evidence for PAR interactions with members of their own family, as well as with other types of receptors.

August 2022 "As the only member of the CX3C chemokine receptor subfamily, CX3CR1 binds to its sole endogenous A much smaller conformational change of helix VI upon activation than previously solved class A GPCR-Gi Thus, our data deepen the understanding of cholesterol modulation in GPCR (G protein-coupled receptor ) signaling and provide insights into the diversity of G protein coupling."

San Francisco under the guidance of Professor Shaun Coughlin where she worked on the newly discovered protease-activated Trejo’s research program is to gain a thorough and mechanistic understanding of processes that control cell signaling by protease-activated receptors (PARs) and the impact on vascular inflammation and cancer PARs are GPCRs that are activated through an atypical irreversible proteolytic mechanism. Her laboratory is the recognized expert on protease-activated receptors, particularly PAR1, and over

the common example known at the time, protease activated receptors (PARs). PARs have an N-terminal leader sequence that is clipped by exogenous proteases to reveal a new N-terminus Adhesion GPCRs pre-cleave themselves and the two resultant fragments of the receptor remain together adhesion GPCRs in complex physiological contexts…one being our discovery that GPR56 is the platelet receptor that senses collagen and shear force to initiate the platelet activation program.
