The arrestin superfamily: cone arrestins are a fourth family [PDF]
Arrestins constitute a superfamily of regulatory proteins that down‐regulate phosphorylated G‐protein membrane receptors, including rod and cone photoreceptors and adrenergic receptors. The potential role of arrestin in color visual processes led us to identify a cDNA encoding a cone‐like arrestin in Xenopus laevis, the principle amphibian biological ...

Targeted disruption of β-arrestin 2-mediated signaling pathways by aptamer chimeras leads to inhibition of leukemic cell growth. [PDF]
β-arrestins, ubiquitous cellular scaffolding proteins that act as signaling mediators of numerous critical cellular pathways, are attractive therapeutic targets because they promote tumorigenesis in several tumor models.

The effect of arrestin conformation on the recruitment of c-Raf1, MEK1, and ERK1/2 activation.
Arrestins are multifunctional signaling adaptors originally discovered as proteins that "arrest" G protein activation by G protein-coupled receptors (GPCRs).

An increased vulnerability has been detected after ischemia/reperfusion injury in cardiomyocytes in diabetic patients. Glucagon-like peptide-1 (GLP-1) has been proven to have a notable cardioprotective effect in cardiomyocytes.

Cell-Type-Dependent Metabolic Compensation Preserves Photoreceptor Survival Through Pyruvate Kinase Isoform Balance. [PDF]
We investigated the roles of PKM2, PKM1, and LDHA in retinal metabolism and structural integrity. In the normal retina, these enzymes are maintained at defined levels that support photoreceptor function. Rod‐specific deletion of LDHA, alone or with PKM2, caused age‐dependent degeneration, as PKM1 induction did not reach levels comparable to PKM2.

GPCR Binding and JNK3 Activation by Arrestin-3 Have Different Structural Requirements
Arrestins bind active phosphorylated G protein-coupled receptors (GPCRs). Among the four mammalian subtypes, only arrestin-3 facilitates the activation of JNK3 in cells.
