Genetic and molecular properties of human and rat renin-binding proteins with reference to the function of the leucine zipper motif

Journal of Biochemistry
H InoueY Miyake


The presence of a leucine zipper motif was recognized in the deduced amino acid sequences of human and rat renin-binding proteins (RnBPs) on cloning and sequence analysis of the RnBP cDNAs. The in vitro synthesized RnBPs, with the respective cDNAs, formed heterodimers with porcine renin and homodimers. On comparison of these properties with those of porcine RnBP, the leucine zipper motif was suggested to be a functional domain common to animal RnBPs. In addition to the motif, a hydrophobic domain adjacent to the motif and 10 cysteine residues were also well conserved in the three RnBPs. Moreover, about 85% of their amino acid sequences were identical. The RnBP mRNAs were expressed in the kidneys as the same size of 1.5-kb and the genes are suggested to exist as single copies in the genomes. Despite the high similarities in genetic and molecular properties, the molecular weights of human and rat RnBPs were 43,000, which is 1,000 larger than that of porcine RnBP. The immunoreactivities of human and rat RnBPs toward anti-porcine RnBP antiserum were 88 and 8% that of porcine RnBP, respectively, and the affinities of the two RnBPs for porcine renin were remarkably less than that of porcine RnBP. Moreover, the human and rat RnBP homo...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.
