Figure 4. Relative abundance of
phosphorylated α-crystallin in different regions of bovine and rabbit
lenses. Extracted representative mass spectra of phosphorylation of
intact αA- and αB-crystallin from outer cortex (A, D),
middle cortex (B, E), and outer nucleus (C, F)
of bovine (A-C) and rabbit (D-F) lenses are
shown. Phosphorylation of both subunits of α-crystallin is most
abundant in the middle cortex of bovine and rabbit lenses.
