Two-dimensional gel electrophoresis protein and phosphorylation analysis of the HCl-extracted mineral-related protein fraction. Green fluorescence, protein; red fluorescence, phosphorylated proteins. The numbered regions were selected by the image analysis software as phosphorylated. Bands 3, 4, and 5 all have isoelectric points of pH <4.0. Band 5 contains UTMP16 and UTMP19. Identification of the components of bands 1–4 is the object of the present studies.
