  • nuclear translocation induced by the stimulation of delta-opioid receptor, a member of the GPCR family
  • cytosolic ARRB1 mediates catecholamine-induced activation of AKT and MDM2, whereas nuclear ARRB1 serves as an adaptor for MDM2-dependent ubiquitination of TP53

  • also regulator of beta-adrenergic receptor A and activator of the lymphoid enhancer factor (LEF) transcription factor
  • involved in synaptic transmission in photoreceptor cells
  • playing a crucial role for ubiquitination and down-regulation of the insulin-like growth factor-1 receptor by acting as adaptor for the MDM2 E3 ligase
  • facilitating the recruitment of histone acetyltransferase p300 by selective enrichment at specific promoters such as that of p27 and c-fos
  • having a broad role in the trafficking of integral plasma membrane protein
  • beta-arrestin-mediated signaling regulates protein synthesis
  • required for the maintenance of a ADRB1-EGFR interaction that can direct cytosolic targeting of ERK in response to catecholamine stimulation
  • both ARRB1 and ARRB2 play a novel and shared role in inhibiting G protein-dependent ERK1/2 phosphorylation
  • emerging role of ARRB1 as an E3-ligase adaptor in the nucleus
  • critical role for ARRB1 nuclear localization in scaffolding and transcriptional regulation
  • ARRB1, ARRB2 are cytosolic proteins well-known to participate in G protein-coupled receptor desensitisation and signalling
  • role in promoting thrombus formation, in part through its participation in ITGA2/ITGB3 signalling
  • ARRB1, ARRB2 are now widely accepted as endocytic and signaling adaptors for G protein-coupled receptors (GPCRs), growth factor receptors, and ion channels

  • interacts with ESCRT-0, a protein complex that recognizes and sorts ubiquitinated cargo into the degradative pathway
  • NEDD4 and ARRB1 as key regulators of SLC9A1 ubiquitylation, endocytosis, and function
  • SHH inducing ARRB1 accumulation and localization to the nucleus, where it participates in enhancing expression of CDKN1B, whose accumulation eventually drives granule neuron precursors (CGNPs) cell cycle exit
  • plays a central role in coupling MIF endocytosis to sustained ERK activation
  • represses adipogenesis and inflammatory responses through its interaction with peroxisome proliferator-activated receptor-gamma (PPARG)
  • upon catecholamine stimulation, ARRB1 promotes the interaction of MDM2 and TP53 by acting as an E3 ligase adaptor that facilitates ubiquitination of p53

  • ARRB1 is a nuclear transcriptional regulator of EDN1-induced CTNNB1 signaling
  • dispensable for STAT1 dephosphorylation and the termination of IFNG signaling
