ATP2B2 (ATPase Plasma Membrane Ca2+ Transporting 2): ATP2B2 encodes a calcium pump involved in the regulation of intracellular calcium levels, crucial for a wide range of cellular processes, including signal transduction, muscle contraction, and neurotransmitter release. Mutations in ATP2B2 have been linked to deafness and vestibular disorders, underscoring its role in hearing and balance through the regulation of calcium in sensory hair cells....
