Introduction to Recombinant Human KCNA3 Protein:
Recombinant proteins are proteins that are produced through genetic engineering techniques, where the DNA sequence of a desired protein is inserted into an expression system, such as bacteria or yeast, to produce large quantities of the protein. Recombinant proteins have become essential tools in various fields of science, including biotechnology, medicine, and research.
One such recombinant protein is the Recombinant Human KCNA3 Protein, also known as the voltage-gated potassium channel subunit Kv1.3. This protein belongs to the Kv1 family of voltage-gated potassium channels and plays a crucial role in regulating the electrical activity of cells.
Structure of Recombinant Human KCNA3 Protein:
The Recombinant Human KCNA3 Protein is a transmembrane protein that consists of six membrane-spanning segments, with the N- and C-termini located on the intracellular side. The protein is composed of 501 amino acids and has a molecular weight of 57 kDa. It is encoded by the KCNA3 gene, located on chromosome 1 in humans.
Activity of Recombinant Human KCNA3 Protein:
The primary function of the Recombinant Human KCNA3 Protein is to act as a voltage-gated potassium channel, which means it allows the flow of potassium ions across the cell membrane in response to changes in membrane potential.
