http://purl.uniprot.org/citations/24275569http://www.w3.org/2000/01/rdf-schema#comment"Protein phosphorylation is one of the most common post-translational modifications. It plays key roles in regulating diverse biological processes of liver tissues. To better understand the role of protein phosphorylation in liver functions, it is essential to perform in-depth phosphoproteome analysis of human liver. Here, an enzyme assisted reversed-phase-reversed-phase liquid chromatography (RP-RPLC) approach with both RPLC separations operated with optimized acidic mobile phase was developed. High orthogonal separation was achieved by trypsin digestion of the Glu-C generated peptides in the fractions collected from the first RPLC separation. The phosphoproteome coverage was further improved by using two types of instruments, i.e. TripleTOF 5600 and LTQ Orbitrap Velos. A total of 22,446 phosphorylation sites, corresponding to 6526 nonredundant phosphoproteins were finally identified from normal human liver tissues. Of these sites, 15,229 sites were confidently localized with Ascore≥13. This dataset was the largest phosphoproteome dataset of human liver. It can be a public resource for the liver research community and holds promise for further biology studies.

Biological significance

The enzyme assisted approach enabled the two RPLC separations operated both with optimized acidic mobile phases. The identifications from TripleTOF 5600 and Orbitrap Velos are highly complementary. The largest phosphoproteome dataset of human liver was generated."xsd:string
