Data show subfunctionalized expression of Arr3a in M- and L-cones, and Arr3b in S- and UV-cones, and suggest that Arr3a deficiency is sufficient to reduce temporal contrast sensitivity.
The G-protein coupled receptor, DRD4, requires ARR1 and ARR4 for desensitization and internalization.
Data indicate that In arrestin 3 (显示 ARRB2 ELISA试剂盒) deficient mice, where the alpha2B (显示 ADRA2B ELISA试剂盒) adrenergic receptor has a stronger binding to spinophilin (显示 PPP1R9B ELISA试剂盒), the hypertensive response is enhanced.
rrestin-3 modulates the activity of ubiquitous JNK1 (显示 MAPK8 ELISA试剂盒) and JNK2 (显示 MAPK9 ELISA试剂盒) in non-neuronal cells, impacting the signaling pathway that regulates their proliferation and survival.
Arrestin-2 (显示 ARRB1 ELISA试剂盒) and -3 association with beta(2)-adrenergic receptor (beta2AR (显示 ADRB2 ELISA试剂盒)) significantly enhanced ERK2 (显示 MAPK1 ELISA试剂盒) binding, but showed little effect on arrestin (显示 SAG ELISA试剂盒) interactions with the upstream kinases c-Raf1 (显示 RAF1 ELISA试剂盒) and MEK1 (显示 MAP2K1 ELISA试剂盒).

Data demonstrate that the alpha(2A)AR (显示 ADRA2A ELISA试剂盒) evokes ERK (显示 EPHB2 ELISA试剂盒) phosphorylation through both an arrestin (显示 SAG ELISA试剂盒)/Src (显示 SRC ELISA试剂盒)-dependent and a Src (显示 SRC ELISA试剂盒)-independent pathway, both of which are G protein dependent and converge on the Ras-Raf (显示 RAF1 ELISA试剂盒)-MEK (显示 MDK ELISA试剂盒) pathway.
These results demonstrate previously unknown crucial regulatory mechanisms that alter ARR/GRK expression levels in macrophages that might modify many, if not all, GPCR-mediated innate immune responses.
These results show that, in MA-10 cells, the hLHR activates Fyn (显示 FYN ELISA试剂盒) through an arrestin-3 (显示 ARRB2 ELISA试剂盒)-dependent pathway and that this pathway is a mediator of the hLHR-provoked release of EGF (显示 EGF ELISA试剂盒)-like growth factors.
In the cell membrane, arrestin-3 (显示 ARRB2 ELISA试剂盒) dissociates quickly and almost completely from the Beta2-adrenoceptor.
The 25-amino acid N-domain element of arrestin 3 (显示 ARRB2 ELISA试剂盒) has the highest affinity for JNK3alpha2, suggesting that it is the key site for JNK3alpha2 docking.
arrestin-3 (显示 ARRB2 ELISA试剂盒) regulates the activity of multiple JNK (显示 MAPK8 ELISA试剂盒) isoforms, suggesting that it might play a role in survival and apoptosis of all cell types.
These data suggest cell type- and subcellular compartment-dependent differences in GRK (显示 GRK4 ELISA试剂盒)/arrestin (显示 SAG ELISA试剂盒)-mediated desensitization and signaling.
Silent scaffolds: inhibition OF c-Jun N-terminal kinase 3 (显示 MAPK10 ELISA试剂盒) activity in cell by dominant-negative arrestin-3 (显示 ARRB2 ELISA试剂盒) mutant.
the TGN (显示 TG ELISA试剂盒) acts as a checkpoint for both the recycling and down-regulation of beta1AR (显示 ADRB1 ELISA试剂盒) and arrestin-3 (显示 ARRB2 ELISA试剂盒) not only mediates beta1AR (显示 ADRB1 ELISA试剂盒) endocytosis but also its recycling through the TGN (显示 TG ELISA试剂盒)
PP2A (显示 PPP2R4 ELISA试剂盒) inhibits association between the Na+,K+-ATPase (显示 ATP1A1 ELISA试剂盒) and arrestin (显示 SAG ELISA试剂盒), and diminishes the effect of arrestin (显示 SAG ELISA试剂盒) on Na+,K+-ATPase (显示 ATP1A1 ELISA试剂盒) trafficking.
upon ligand activation, CysLT(1 (显示 CYSLTR1 ELISA试剂盒))R is tyrosine-phosphorylated and released from heterodimers with CysLT(2 (显示 CYSLTR2 ELISA试剂盒))R and, subsequently, internalizes from the plasma membrane to the nuclear membrane in a clathrin-, arrestin-3 (显示 ARRB2 ELISA试剂盒)-, and Rab-5 (显示 RAB5A ELISA试剂盒)-dependent manner
The agonist-induced internalization of GPR109A receptors is regulated by GRK2 (显示 ADRBK1 ELISA试剂盒) and arrestin3 in a pertussis toxin-sensitive manner and that internalized receptor recycling is independent of endosomal acidification.
two non-visual arrestins, arrestin2 and arrestin3, localize to the centrosome, a key organelle involved in microtubule nucleation and bipolar mitotic spindle assembly
K2A mutations in arrestin-1 (显示 SAG ELISA试剂盒), -2, and -3 significantly reduced their binding to active phosphorhodopsin.
multiple residues on the non-receptor-binding side of arrestin-3 (显示 ARRB2 ELISA试剂盒) are crucial for JNK3 (显示 MAPK10 ELISA试剂盒) activation
Both nonvisual arrestin-2 (显示 ARRB1 ELISA试剂盒) and arrestin-3 (显示 ARRB2 ELISA试剂盒) are shown to directly bind Jun kinase (JNK)3alpha2 and its upstream activator Map kinase (显示 MAPK1 ELISA试剂盒) kinase (MKK)4 (显示 MAP2K4 ELISA试剂盒); the affinity of arrestin-3 (显示 ARRB2 ELISA试剂盒) for these kinases is higher than that of arrestin-2 (显示 ARRB1 ELISA试剂盒).
