FAST ATOM BOMBARDMENT MASS SPECTROMETRY (FABMS) ANALYSIS OF AN N- TERMINAL - BLOCKED PEPTIDE
FABMS analysis of T-lb peptide before and after one cycle of Edman degradation indicated an unblocked N-terminal Thr residue for this tryptic peptide. In contrast , our data showed a molecular protonated ion, MH + for T- la peptide at 655 mass units (mu) which is 42 mu higher than the MH ion of T- 1b peptide. In addition, T- la peptide was not amenable to one cycle of manual Edman degrada...
متن کاملIdentification of an HLA-A2-Restricted Epitope Peptide Derived from Hypoxia-Inducible Protein 2 (HIG2)
We herein report the identification of an HLA-A2 supertype-restricted epitope peptide derived from hypoxia-inducible protein 2 (HIG2), which is known to be a diagnostic marker and a potential therapeutic target for renal cell carcinoma. Among several candidate peptides predicted by the HLA-binding prediction algorithm, HIG2-9-4 peptide (VLNLYLLGV) was able to effectively induce peptide-specific...
متن کاملThe N–Terminal Tail of hERG Contains an Amphipathic α–Helix That Regulates Channel Deactivation
The cytoplasmic N-terminal domain of the human ether-a-go-go related gene (hERG) K+ channel is critical for the slow deactivation kinetics of the channel. However, the mechanism(s) by which the N-terminal domain regulates deactivation remains to be determined. Here we show that the solution NMR structure of the N-terminal 135 residues of hERG contains a previously described Per-Arnt-Sim (PAS) d...
متن کاملPseudo-phosphatase Sbf1 contains an N-terminal GEF homology domain that modulates its growth regulatory properties.
Sbf1 (SET binding factor 1) is a pseudo-phosphatase related to the myotubularin family of dual specificity phosphatases, some of which have been implicated in cellular growth and differentiation by virtue of their mutation in human genetic disorders. Sbf1 contains germline-encoded alterations of its myotubularin homology domain that render it non-functional as a phosphatase. We report here the ...
متن کاملEvaluation of Serum Levels of N-terminal Pro Brain Natriuretic Peptide and Atrial Natriuretic Peptide in Neonates with Respiratory Distress
Background: Acute respiratory distress (ARD) is a critical respiratory failure due to lung injury of neonates leading to the clinical appearance of poor lung compliance. The aimed of the study was to evaluate the diagnostic values in differentiating respiratory from heart diseases with using of N-terminal pro brain natriuretic peptide (NT-pro BNP) and Atrial natriuretic peptide(ANP) in neonates...
