Abstract
![]()
We report a novel hybrid, molecular
and elemental mass spectrometry
(MS) setup for the absolute quantification of snake venom proteomes
shown here for two desert black cobra species within the genus Walterinnesia, Walterinnesia aegyptia and Walterinnesia morgani. The experimental
design includes the decomplexation of the venom samples by reverse-phase
chromatography independently coupled to four mass spectrometry systems:
the combined bottom-up and top-down molecular MS for protein identification
and a parallel reverse-phase microbore high-performance liquid chromatograph
(RP-μHPLC) on-line to inductively coupled plasma (ICP-MS/MS)
elemental mass spectrometry and electrospray ionization quadrupole
time-of-flight mass spectrometry (ESI-QToF MS). This allows to continuously
record the absolute sulfur concentration throughout the chromatogram
and assign it to the parent venom proteins separated in the RP-μHPLC-ESI-QToF
parallel run via mass profiling. The results provide a locus-resolved
and quantitative insight into the three desert black cobra venom proteome
samples. They also validate the units of measure of our snake venomics
strategy for the relative quantification of snake venom proteomes
as % of total venom peptide bonds as a proxy for the % by weight of
the venom toxins/toxin families. In a more general context, our work
may pave the way for broader applications of hybrid elemental/molecular
MS setups in diverse areas of proteomics.

Abstract
Intrinsically disordered proteins (IDPs) do not have rigid 3D structures, showing changes in their folding depending on the environment or ligands. Intrinsically disordered proteins are widely spread in eukaryotic genomes, and these proteins participate in many cell regulatory metabolism processes. Some IDPs, when aberrantly folded, can be the cause of some diseases such as Alzheimer′s, Parkinson′s, and prionic, among others. In these diseases, there are modifications in parts of the protein or in its entirety. A common conformational variation of these IDPs is misfolding and aggregation, forming, for instance, neurotoxic amyloid plaques. In this review, we discuss some IDPs that are involved in neurodegenerative diseases (such as beta amyloid, alpha synuclein, tau, and the “IDP-like” PrP), cancer (p53, c-Myc), and diabetes (amylin), focusing on the structural changes of these IDPs that are linked to such pathologies. We also present the IDP modulation mechanisms that can be explored in new strategies for drug design. Lastly, we show some candidate drugs that can be used in the future for the treatment of diseases caused by misfolded IDPs, considering that cancer therapy has more advanced research in comparison to other diseases, while also discussing recent and future developments in this area of research. Therefore, we aim to provide support to the study of IDPs and their modulation mechanisms as promising approaches to combat such severe diseases.
