GNB5 (G Protein Subunit Beta 5): GNB5 is a component of heterotrimeric G proteins, which mediate various cellular responses to external stimuli through signal transduction pathways. It is involved in regulating heart rate, vision, and neurotransmission, highlighting its importance in both the central and peripheral nervous systems. Mutations in GNB5 are associated with arrhythmias and neurodevelopmental disorders, making it a key subject for studies on signal transduction and its related pathologies....
