Fish Parvalbumin (PV), also referred to as fish parvalbumin antigen, is a small, water-soluble calcium-binding protein widely distributed in fish muscle. It is recognized as the predominant allergen in fish allergies.

Within fish tissue, PV is primarily concentrated in the skeletal white muscle, accounting for approximately 0.3% of the total fish protein. The most distinguishing characteristic of this protein is its exceptional stability: it retains its structural integrity at temperatures exceeding 80°C and is resistant to both extreme pH levels and proteolytic digestion. Consequently, it maintains its allergenic potential even after extensive food processing.

The core physiological function of fish parvalbumin involves regulating calcium ion concentration to promote muscle relaxation following contraction, making it a vital component of the calcium signaling pathway.
