kinases (GRKs) and subsequent recruitment of β-arrestins, resulting in receptor internalization into endosomes has been extended by discovering that some internalized GPCRs continue to signal via G proteins from endosomes the parathyroid hormone (PTH) type 1 receptor (PTHR), which engages on sustained cAMP signaling from endosomes This mini-review discusses recent insights into the mechanisms of PTHR endosomal signaling and its physiological

protein complex in neurotransmitter release has been well characterized, the mechanisms that modulate the delivery molecular players, including SNARE proteins; here, SNARE proteins play a role in the fusion of recycling endosomes

GPCRs, G proteins, and arrestins on endosomal membranes3,4. Furthermore, targeting GPCRs in specific cellular compartments requires precise delivery mechanisms to This may involve the development of specialized delivery vehicles, such as nanoparticles or liposomes expressed in cellular compartments require innovative approaches to overcome barriers related to stability, delivery Towards a molecular understanding of endosomal trafficking by Retromer and Retriever.

the cellular biology of G protein-coupled receptors (GPCRs) about a novel biosensor shed light on the endosomal , published in Nature Chemical Biology, highlights the role of the chaperone protein DNAJC13 in the endosomal-lysosomal During this process, APEX2 can label proteins in the vicinity, allowing the capture of a snapshot of the endosomal Finally, this analysis provided insights into the molecular composition of the endosomal environment

The signaling profile of CXCR3 changes as it traffics from the plasma membrane to endosomes in a ligand-specific Endosomal signaling is critical for biased activation of G proteins, β-arrestins, and extracellular-signal-regulated

HEK293 and Huh-7-Lunet cells after activation by glucagon within 5 min and transit via EEA1-marked endosomes Together, these results implicate the endosomal signaling paradigm in metabolic regulation by glucagon

Using fast recycling, slow recycling, and late endosomal recycling markers, CCR2 was also shown to be rapidly sorted into fast-recycling Rab4-positive endosomes in a more sustained manner compared to the atypical scavenging receptor ACKR3, and Rab7-positive late endosomes.
