Recombinant Human Parvalbumin

Source : Escherichia Coli. PVALB Human Recombinant fused with a 24 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 134 amino acids (1-110 a.a.) and having a molecular mass of 14.6kDa. The PVALB is purified by proprietary chromatographic techniques. Parvalbumin alpha (PVALB) is a member of a larger group of EF hand proteins. PVALB is a high affinity calcium ion-binding protein which is structurally and functionally similar to calmodulin and troponin C. Parvalbumin is expressed in a specific population of GABAergic interneurones which are believed to have a role in maintaining the balance between excitation and inhibition in the cortex as well as the hippocampus.
