The interplay between various types of PTMs is often poorly understood beyond the Histone code, and yet various disease etiologies can be dictated by subtle changes in a single post-translational event [Citation199,Citation200]. Drug discovery is a lengthy and highly expensive process that uses a variety of tools from diverse fields. With rapid advancements in the RNA sequencing field, proteogenomics has been shown to be a power tool allowing the generation of customized protein sequence databases using genomic and transcriptomic information.

Single molecule protein detection is currently possible through DNA-linked antibodies [Citation30] or fluorescently-labeled protein specific aptamers [Citation31]. The first step is to define the intended use of the biomarker. In many cases, prior knowledge can inform this decision, pointing toward high sensitivity methods for example if chemokines and cytokines are likely potential biomarkers. USA 106, 2198421989 (2009).

Identification of a novel mitochondrial protein (mitoNEET) cross-linked specifically by a thiazolidinedione photoprobe. It should be noted that for the notoriously challenging task of efficacy target identification in phenotypic drug discovery, chemoproteomics is often and most successfully used as part of a multipronged strategy that also includes functional genetic, cellular profiling and computational approaches to generate as much complementary information as possible to hone in on the efficacy target amongst the hit lists of physical and functional interactors [Citation7274]. Biochemistry 46, 350358 (2007). More specific approaches may be applicable in certain cases, such as the use of TAILS to identify novel protease substrates as discussed previously [Citation145].
