Sequential algorithmic modification with test data reuse [PDF]
arXiv, 2022 After initial release of a machine learning algorithm, the model can be fine-tuned by retraining on subsequently gathered data, adding newly discovered features, or more. Each modification introduces a risk of deteriorating performance and must be validated on a test dataset.

Casein Kinase II Phosphorylation of Spt6 Enforces Transcriptional Fidelity by Maintaining Spn1-Spt6 Interaction [PDF]
, 2018 Spt6 is a histone chaperone that associates with RNA polymerase II and deposits nucleosomes in the wake of transcription. Although Spt6 has an essential function in nucleosome deposition, it is not known whether this function is influenced by post ...

Orchestrating the proteome with post-translational modifications [PDF]
Journal of Experimental Botany, 2018 Post-translational modifications (PTMs) add tremendous complexity to cellular proteomes. The large variety of these modifications and their concurrent appearance in proteins dramatically increase the proteome size from mere thousands to the order of millions of possible protein forms.

Post-translational modifications and their implications in cancer
Frontiers in Oncology, 2023 Post-translational modifications (PTMs) are crucial regulatory mechanisms that alter the properties of a protein by covalently attaching a modified chemical group to some of its amino acid residues. PTMs modulate essential physiological processes such as signal transduction, metabolism, protein localization, and turnover and have clinical relevance in ...

Evaluating Mechanisms of IDH1 Regulation through Site-Specific Acetylation Mimics
Biomolecules, 2021 Isocitrate dehydrogenase (IDH1) catalyzes the reversible NADP+-dependent oxidation of isocitrate to α-ketoglutarate (αKG). IDH1 mutations, primarily R132H, drive > 80% of low-grade gliomas and secondary glioblastomas and facilitate the NADPH-dependent ...

Deciphering post‐translational modification codes [PDF]
FEBS Letters, 2013 Post‐translational modifications (PTMs) occur on nearly all proteins. Many domains within proteins are modified on multiple amino acid sidechains by diverse enzymes to create a myriad of possible protein species. How these combinations of PTMs lead to distinct biological outcomes is only beginning to be understood.

Post-translational modifications in neurodegeneration
AIMS Biophysics, 2015 Post-translational modifications increase proteome functionality for managing all aspects of normal cell biology. They are based on the covalent attachment of functional groups, leading to phosphorylation, acetylation, glycosylation, acylation, ubiquitination, SUMOylation and oxidation of protein targets.
