Coatomer protein complex subunit a (COPA) is a 160kDa protein with 1224 amino acids. The gene encoding it is localized on human chromosome 1q23.2.
Synonyms: Anti-HEP-COP; Anti-coatomer protein complex, subunit α
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: Coatomer protein complex subunit a (COPA) regulates intracellular protein transport between the endoplasmic reticulum and the cis-Golgi. It also controls intra-Golgi trafficking. The protein functions in early endosome maturation and modulates the entry of arginine-rich peptides into the cell.
