In molecular biology Pertactin (PRN) is a highly immunogenic virulence factor of Bordetella pertussis a bacterium that causes pertussis. Specifically it is an outer membrane protein that promotes adhesion to tracheal epithelial cells. PRN is purified from Bordetella pertussis and is used for the vaccine production as one of the important components of acellular pertussis vaccine.A large part of the N-terminus of the Pertactin protein is composed of beta helix repeats.
