Cyclic nucleotide specificity of the activator and catalytic sites of a cGMP-stimulated cGMP phosphodiesterase from Dictyostelium discoideum [PDF]

, 1985
The cellular slime mold Dictyostelium discoideum has an intracellular phosphodiesterase which specifically hydrolyzes cGMP. The enzyme is activated by low cGMP concentrations, and is involved in the reduction of chemoattractant-mediated elevations of ...

Removal of dsRNA byproducts using affinity chromatography

Molecular Therapy: Nucleic Acids
Double-stranded RNA (dsRNA) molecules are immunogenic byproducts of in vitro transcription of single-stranded RNA (ssRNA). Removal of dsRNA from ssRNA is difficult because the byproducts have similar sizes, sequences, and charges to the desired ssRNA ...

Purification of rabbit serum histidine-proline-rich glycoprotein via preparative gel electrophoresis and characterization of its glycosylation patterns. [PDF]

PLoS ONE, 2017
Histidine-Proline-rich Glycoprotein (HPRG) is a plasma protein of vertebrates and several marine bivalves. Due to its multidomain structure consisting of several regions HPRG can interact with a variety of ligands, however the exact physiological role ...

Surface Mutation Thr34His Facilitates Purification of Haemophilus influenza Carbonic Anhydrase via Metal Affinity Chromatography [PDF]

, 2017
In order to pursue Haemophilus influenza carbonic anhydrase (HICA) as a potential drug target, easy and efficient purification methods must be developed. While immobilized metal affinity chromatography (IMAC) may be used, complications with polyhistidine

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Analysis of free analyte fractions by rapid affinity chromatography [PDF]

, 2004
The invention is generally directed toward an analytical method to determine the concentration of the free analyte fraction in a sample. More particularly, the method encompasses applying a sample comprising a free and bound analyte fraction to an ...
