Our data reveal beta-arrestin 1, beta-arrestin 2 (show ARRB2 Antibodies), and AT1R (show AGTRAP Antibodies) as key regulatory molecules in the Frank-Starling mechanism, which involves length-dependent enhancement of cardiac myofilament Ca(2 (show CA2 Antibodies)+) sensitivity.
Arrb1 reduced the chemotherapy-induced Lgr5 (show LGR5 Antibodies) stem cell apoptosis by inhibiting endoplasmic reticulum stress-mediated mitochondrial apoptotic signaling.
findings suggest that knockdown of beta-arrestin 1 can suppress glioblastoma multiforme cell proliferation, invasion and glycolysis by inhibiting Src (show SRC Antibodies) signaling

Study reports an X-ray free electron laser crystal structure of the rhodopsin (show RHO Antibodies)-arrestin (show SAG Antibodies) complex, in which the phosphorylated C terminus of rhodopsin (show RHO Antibodies) forms an extended intermolecular beta sheet with the N-terminal beta strands of arrestin (show SAG Antibodies). Phosphorylation was detected at rhodopsin (show RHO Antibodies) C-terminal tail residues T336 and S338.
Beta-arrestin-1 with beta-arrestin-2 shared common mechanisms to suppress podocyte autophagy by negative regulation of ATG12-ATG5 conjugation.
data suggest that beta-arr1 mediated nuclear signaling regulates the production of excretive factors derived from niche astrocytes and expansion of neural precursors in DG, thus maintaining homeostasis of adult hippocampal neurogenesis
beta-arr1 (show SAG Antibodies) has a critical role in modulating ERK (show EPHB2 Antibodies), JNK (show MAPK8 Antibodies) and p38 MAPK (show MAPK14 Antibodies) pathways mediated by TNF-alpha (show TNF Antibodies) in intestinal epithelial cells.
COX-2-derived PGE2 inhibits IL-10 expression in brain microglia through a novel EP2- and beta-arrestin-dependent signaling pathway.
Results indicate a mechanism for beta-arrestin1 in the regulation of the prostate cancer procession through inhibiting FOXO3a (show FOXO3 Antibodies).
The results show that PTEN controls multicellular assembly through a membrane-associated regulatory protein complex composed of beta-Arrestin1, ARHGAP21 (show ARHGAP21 Antibodies) and Cdc42 (show CDC42 Antibodies).
These results provide clear evidence that CXCR4- or CCR5-beta-arrestin complexes induce receptor endocytosis and signaling in the absence of G protein coupling and ligand-induced conformational changes of the receptor.
Our results identify a new molecular mechanism involving miR (show MLXIP Antibodies)-326 and Arrb1 as regulators of Sonic hedgehog (show SHH Antibodies) medulloblastoma Cancer stem cells . Specifically, low levels of Arrb1 and miR (show MLXIP Antibodies)-326 trigger and maintain Hh/Gli (show GLI1 Antibodies) signaling and self-renewal
This work demonstrates that the expression of FSHR (show FSHR Antibodies) and LHCGR (show LHCGR Antibodies) can be induced in hGL5 cells but that the FSHR (show FSHR Antibodies)-dependent cAMP/PKA pathway is constitutively silenced, possibly to protect cells from FSHR (show FSHR Antibodies)-cAMP-PKA-induced apoptosis.
This study reveals contrasting abilities of IGF-1R (show IGF1R Antibodies) to interact with each b-arrestin (show SAG Antibodies) isoform, depending on the presence of the ligand and demonstrates the antagonism between the two b-arrestin (show SAG Antibodies) isoforms in controlling IGF-1R (show IGF1R Antibodies) expression and function, which could be developed into a practical anti-IGF-1R (show IGF1R Antibodies) strategy for cancer therapy.
Lowering the level of cellular FLNA caused an elevation in RalA activity and resulted in selective interference with the normal intracellular trafficking and signaling of D3R through beta-arrestins.
the depleted beta-Arrestin1 reduced the interaction of P300 (show EP300 Antibodies) with Sp1 (show PSG1 Antibodies), thus to reduce Sp1 (show PSG1 Antibodies) binding to hTERT promoter, downregulate hTERT transcription, decrease telomerase activity, shorten telomere length, and promote Reh (show CES1 Antibodies) cell senescence.

Study demonstrated that beta-arrestin1 is critically involved in zebrafish primitive hematopoiesis, where beta-arrestin1 binds to and sequesters the PcG recruiter YY1 (show YY1 Antibodies), thus relieving PcG-mediated repression of cdx4-hox (show MSH2 Antibodies) pathway.
The identified receptor-phospho-selective mechanism for arrestin (show SAG Antibodies) conformation and the spacing of the multiple phosphate-binding sites in the arrestin (show SAG Antibodies) enable arrestin (show SAG Antibodies) to recognize plethora phosphorylation states of numerous GPCRs.
The presented functional map quantitatively connects critical interactions in the polar core and along the C tail of arrestin (show SAG Antibodies).

Members of arrestin/beta-arrestin protein family are thought to participate in agonist-mediated desensitization of G-protein-coupled receptors and cause specific dampening of cellular responses to stimuli such as hormones, neurotransmitters, or sensory signals. Arrestin beta 1 is a cytosolic protein and acts as a cofactor in the beta-adrenergic receptor kinase (BARK) mediated desensitization of beta-adrenergic receptors. Besides the central nervous system, it is expressed at high levels in peripheral blood leukocytes, and thus the BARK/beta-arrestin system is believed to play a major role in regulating receptor-mediated immune functions. Alternatively spliced transcripts encoding different isoforms of arrestin beta 1 have been described.
