ARRB1 (Arrestin Beta 1) is a protein that plays a crucial role in regulating G protein-coupled receptor (GPCR) signaling. It is involved in the desensitization and internalization of activated GPCRs, helping to deactivate downstream signals. ARRB1 is essential for processes such as sensory perception, neurotransmission, and hormonal regulation.
