The availability of core classes that represent modifications, peak annotations and chemical entities in a proteomics context, makes JPL the ideal framework to compute physicochemical properties, such as isoelectric point (pI), retention time (RT) and gravy index.
In contrast, some evidence suggests that these tissues represent modifications in molecular level resembling tumor tissues [ 19].
Epigenetic changes, which represent reversible modifications that affect gene expression without altering the DNA sequence itself, are also a hallmark of cancer [4], [5].
Composition rules are generated only once, are aggregated over time, and represent all formally correct modifications that were identified by the composition module so far.
NF-Y colocalizes with nascent RNA, while RNA polymerase II is I phosphorylated on serine 2 of the YSPTSPS repeats within its carboxyterminal domain and histones are carrying modifications that represent activation signals of gene expression (H3K9ac and PAN-H4ac).
Phosphorylation and proteolysis are two widespread covalent post-translational modifications that represent important regulatory mechanisms in biology.
Moreover, the technologies that have been utilized for discovery, particularly in the early days of proteomics, lacked sufficient depth to allow exploration of low abundance proteins and their modifications that represent a potentially rich source of biomarkers [ 4].
In a few instances, however, studies have demonstrated taxon-specific physiological modifications that appear to represent evolutionary adaptations to aquatic life in ectotherms.
These family members have evidence of telomere shortening in the absence of a TERT mutation; their telomere shortening represents an epigenetic modification that has been stably inherited from the parent with a TERT mutation.
In this section, we examine several modifications that change the characteristic of the synthesis step by representing the elongation process in more detail.
The union does not allow contract modifications that lower the value of a player's contract, and deferring payment would theoretically represent that.
