The assembly of spliceosomal U-rich small nuclear ribonucleoproteins (U snRNPs) is an ATP-dependent process mediated by the coordinated action of the SMN and the PRMT5 complex. Here, we provide evidence that the activity of this assembly machinery is regulated by means of post-translational modification. We show that two main components of the SMN/PRMT5(More)
Synthetic RS20 peptide and a set of its point-mutated peptide analogs have been used to analyze the interactions between calmodulin (CaM) and the CaM-binding sequence of smooth-muscle myosin light chain kinase both in the presence and the absence of Ca(2+). Particular peptides, which were expected to have different binding strengths, were chosen to address(More)
The output signal generated by detectors used in ion mobility spectrometry (IMS) is a time-dependent, small ionic current. To be able to take full advantage of information contained in this signal, adequate procedures of signal processing need to be utilized. Methods of spectrum filtration, peak separation, base-line correction as well as one- and(More)
