Polypeptide Hormone Receptors
The advent of ultramicroscale purification and analysis technology, along with gene manipulation techniques, has greatly accelerated progress in molecular cell biology. (We used to call this "Biochemistry.") Nowhere is the rate of progress more impressively evident than in the field of hormone receptor study, where the enthusiastic research of numerous investigators is rapidly clarifying struct...
متن کاملPolypeptide hormone interaction. 3. Conformational changes of glucagon bound to lysolecithin.
The Turner 210 spectrofluorometer was used for fluorescence mea;;urements. The Cary model 15 spectrophotometer was used to obtain absorption and difference spectra. A Cary 60 spectropolarimeter, equipped with a Pockels cell, was used to measure circular dichroism. Solutions had optical densities, in the wave length region of measurement, below 2.0. The data are reported as mean residue elliptic...
متن کاملInteraction of a new polypeptide with yeast RNA polymerase B.
A basic 37,000-dalton protein (P37), purified from yeast cells, interacts with yeast RNA polymerase B and drastically increases its specific activity. A complex of P37 and RNA polymerase can be isolated by sedimentation through a glycerol gradient. The complex is dissociated at the ionic strength of 0.9. The preferential binding of P37 with RNA polymerase form BI (with the unproteolyzed B220 su...
متن کاملInteraction of alytic polypeptide, melittin, with lipid membrane systems.
To study mechanisms whereby lytic proteins disrupt biomembranes, artificial phospholipid spherules (liposomes) were exposed to melittin, a cationic peptide in which sequences of hydrophobic (Positions 1 to 20) and hydrophilic (Positions 21 to 26) amino acids are unequally distributed. At concentrations above 1OF M, melittin, which is the major toxin of bee venom, released marker anions (CrOb) o...
متن کاملinteraction between her-2 and hormone receptors in breast cancer
introduction: breast cancer is the most common malignancy with more than one million new cases diagnosed annually all around the world. its growth is mostly regulated by steroid hormones such as estrogen and peptide growth factors in interaction with epidermal growth factor 1 and 2. methods and materials: in this study, 237 patients who had consulted the oncology clinic of tabriz university of ...
