XMEs detected in liver but not detected in whole skin. Protein identification was based on the presence of ≥2 different tryptic peptides.

The proteins identified have been classified into functional groups. The corresponding NCBI numbers are indicated for each protein and for all members of groups of related proteins. The sub-cellular fraction in which they were principally detected is shown. The proportion of liver samples (n = 5) in which each protein was identified is indicated.
