the vasopressin v2 receptor belongs to the large family of the g-protein coupled receptors and is responsible for the antidiuretic effect of the neurohypophyseal hormone arginine vasopressin (avp). based on bioinformatic studies it seems that ala300 and asp297 of the v2 vasopressin receptor (v2r) are involved in receptor binding. ala300glu mutation resulted in lower energy while asp297tyr mutat...

Hypertrophic cardiomyopathy is a primary cardiac disease, characterised by idiopathic myocardial hypertrophy, and is caused by defects in sarcomeric protein encoding genes. One of these genes is cardiac myosin binding protein C (MyBP-C), in which a number of splice site and duplication mutations causing HCM have been described. During mutation screening of a South African HCM population by PCR-...

The microtubule-associated protein, doublecortin-like kinase 1 (DCLK1), is highly expressed in a range of cancers and prominent therapeutic target for inhibitors. physiological roles DCLK1 activity how it regulated remain elusive. Here, we analyze the role mammalian regulating microtubule binding. We found that autophosphorylates residue within its C-terminal tail to restrict prevent aberrant h...

Horseradish peroxidase (HRP), has gained significant interests in biotechnology, especially in biosensor field and diagnostic test kits. Hence, its solvent-exposed lysine residues 174, 232, and 241 have been frequently modified with the aim of improving its stability and catalytic efficiency. In this computational study, we investigated the effects of Lys-to-Glu substitutions on HRP structure t...

background: the purity and correct folding of a recombinant protein is critical for any structural, biochemical and vaccine design studies. plasmodium vivax duffy binding protein-ii is a leading vaccine candidate for vivax malaria. in the present study, the purification process of recombinant dbp-ix (a variant form of pvdbp-ii) was optimized to achieve the highest yield and purity. moreover, na...

Cystic fibrosis (CF) is the most common severe autosomal recessive disorder caused by a wide spectrum of mutations in the gene encoding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The frequencies, types and distributions of mutations vary widely between different populations and ethnic groups. The aim of this study was to perform a comprehensive analysis of the C...

Familial hypertrophic cardiomyopathy is a disease generally believed to be caused by mutations in sarcomeric proteins. In a family with hypertrophic cardiomyopathy linked to polymorphic markers on chromosome 11, we found a new mutation of a splice donor site of the cardiac myosin-binding protein-C gene. This mutation causes the skipping of the associated exon in mRNA from lymphocytes and myocar...

A binding study of nickel ions by a new recombinant human Growth Hormone (hGH), produced as an injected drug, has been done at 27˚C in NaCl solution (50 mM) using an isothermal titration calorimetry. There is a set of three identical and non-interacting binding sites for nickel ions. The intrinsic dissociation equilibrium constant and the molar enthalpy of binding are 40 μM and -16...
