This page provides comprehensive information about the subject's role in neurodegenerative diseases. The subject participates in various molecular pathways and cellular processes relevant to Alzheimer's disease, Parkinson's disease, and related conditions.
ARRB1 is a 418 amino acid protein with a characteristic arrestin fold. It contains two domains connected by a flexible hinge region.
ARRB1 binds to phosphorylated GPCRs to prevent further G protein activation and promotes receptor internalization. It also acts as a signaling scaffold.
ARRB1 dysregulation is implicated in Alzheimer's and Parkinson's disease through effects on neurotransmitter receptor signaling.
No specific therapies. Understanding arrestin biology may lead to biased ligand development.
