Gene Information
human ... CNN1(1264)
General description
The gene CNN1 (calponin 1) encodes a 34kDa protein that has some sequence similarity with cardiac troponin I and T. It is mainly present in the cytoskeleton and contractile apparatus of differentiated smooth muscle cells. Calponin has three isoforms, calponin-1 (basic), 2 (neutral), and 3 (acidic). These isoforms have a conserved amino-terminal region containing calponin homology (CH)3 domain and a troponin I-like/actin-binding domain.
Immunogen
Calponin-1 recombinant protein epitope signature tag (PrEST)
Application
Anti-CNN1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem/physiol Actions
Calponin 1 is an actin-binding protein that is specific to smooth muscle cells. It serves as a marker for differentiation of smooth muscle cells. It may participate in the regulation of smooth muscle contraction by negatively regulating the actin-activated ATPase activity of myosin. It also binds to tropomyosin and calmodulin-binding protein. In vitro, it has the ability to interact with cytoskeletal components, such as myosin, caldesmon, desmin and tubulin. It participates in agonist-induced signal transduction in smooth muscle cells. The amino-terminal CH domain of this protein associates with extracellular regulated Ser/Thr kinases (ERK1 and ERK2) via PKC (protein kinase C). The protein plays an important role in cytoskeletal organization and development of vasculature.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

Matrix metalloproteinase (MMP)-2 is activated in aorta during endotoxemia and plays a role in the hypocontractility to vasoconstrictors. Calponin-1 is a regulator of vascular smooth muscle tone with similarities to troponin, a cardiac myocyte protein that is cleaved by MMP-2

Calponin 2 (h2 calponin, CNN2) is an actin-binding protein implicated in cytoskeletal organization. We have found that the expression of calponin 2 is relatively restricted to vasculature from 16 to 30 h post-fertilization during zebrafish (Danio rerio) development. Forty-eight hours
