Parvalbumin
![Parvalbumin is involved in prey recognition in Thamnophiine snakes: A Nerodia fasciata can be seen here first licking a parvalbumin-coated lure, then attempting to prey on it.[2]](/uploads/202502/01/-Chemical-Basis-of-Prey-Recognition-in-Thamnophiine-Snakes-The-Unexpected-New-Roles-of-Parvalbumins-pone.0039560.s001.ogv5240.jpg)
Parvalbumin is a calcium-binding albumin protein with low molecular weight (typically 9-11 kDa).
It has three EF hand motifs and is structurally related to calmodulin and troponin C. Parvalbumin is localised in fast-contracting muscles, where its levels are highest, as well as in the brain and some endocrine tissues.
