Protein Isoforms and Isozymes

Peter W. Gunning

Open publisher page 17 citations

Abstract

Abstract Isoforms are highly related gene products that perform essentially the same biological function. Isozymes are isoforms of an enzyme. Isoforms can differ in their biological activity, regulatory properties, temporal and spatial expression, intracellular location or any combination thereof. Isoforms are almost always either the products of one gene or of multiple genes that evolved from a single ancestor gene.
