In addition to the Ren-1 gene common to all mice, some inbred strains carry a second copy of the renin structural gene, Ren-2. These two loci are tightly linked genetically on mouse chromosome one. We have used pulsed field gel electrophoresis (PFGE) to study the physical arrangement of the two renin genes in the inbred strain DBA/2. PFGE mapping permitted the construction of a restriction map of the Ren loci spanning roughly 120 Kb. The results indicate that the genes are transcribed in the same relative direction, that Ren-2 lies upstream relative to Ren-1, and that the respective coding sequences are separated by approximately 20 Kb.

D012083	Renin	A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.

D004262	DNA Restriction Enzymes	Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.
