ATPase, Na+/K+ Transporting Beta 3 Polypeptide (ATP1B3) Antibody

Background

The ATPase Na+/K+ transporting subunit beta 3 (ATP1B3) is a critical protein involved in maintaining cellular ionic balance through the sodium-potassium (Na+/K+) pump, an essential enzyme for cellular homeostasis. ATP1B3 is one of the beta subunits of this Na+/K+-ATPase complex, which actively transports sodium (Na+) out of cells and potassium (K+) into cells against their concentration gradients using energy from ATP hydrolysis. The proper functioning of this pump is vital for generating the membrane potential, controlling cell volume, and enabling various cellular processes such as nerve impulse transmission, muscle contraction, and maintaining cell polarity. ATP1B3 is expressed in many tissues, particularly in those involved in high rates of ion transport, such as neural, cardiac, and renal tissues.
