4.1.2 Functional protein microarray
The emergence of protein domains with full-length functionality provides
a way forward for Functional protein microarrays. The protein chips are
utilized in a single experiment to examine the biochemical functions of
the whole proteome [47]. Purified proteins are now being used to
create functional protein microarrays, that allows to study the protein
interactions with protein, lipid, drug, DNA and RNA. In yeast, protein
kinases substrate specificity was first analyzes using functional
protein microarray. Protein functions and disease biomarkers are now
identified via functional protein microarray [49].
