ARRB1 (Arrestin Beta 1): ARRB1 is a protein involved in the regulation of G protein-coupled receptor (GPCR) signaling. It plays a crucial role in the desensitization and internalization of activated GPCRs, contributing to the termination of downstream signaling. ARRB1 is essential for various physiological processes, including sensory perception, neurotransmission, and hormonal responses....
