Any process that modulates the force with which blood travels through the circulatory system. The process is controlled by a balance of processes that increase pressure and decrease pressure.
Chromogranin A is an acidic protein, stored and released with catecholamines, and is overexpressed in genetic hypertension. In the human genome, its locus has previously been positioned on the long arm of Chromosome 14 in the 14q32 region. As a first step toward evaluating its potential linkage with hereditary hypertension, we determined its chromosomal position in mouse and rat. Chromogranin A was present as a single-copy gene in both mouse and rat. Analysis of the allele distribution in an interspecific mouse backcross by single-strand conformation polymorphism positioned the chromogranin A locus on Chromosome 12, between Igh-C and D12Pas1. Evaluation of a rat/mouse somatic cell hybrid panel indicated that chromogranin A is on rat Chromosome 6. In each case (mouse, rat, and human), chromogranin A is in a conserved region with nearby markers including the immunoglobulin heavy chain locus.
A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
