Calponin 1 is a basic smooth muscle protein that in humans is encoded by the CNN1gene.[5]
The CNN1 gene is located at 19p13.2-p13.1 in the human chromosomal genome and contains 7 exons, encoding the protein calponin 1, an actin filament-associated regulatory protein.[6] Human calponin 1 is a 33.2-KDa protein consists of 297 amino acids with an isoelectric point of 9.1,[7] thus calponin 1 is also known as basic calponin.
