Figure 3From: Shift in the isoelectric-point of milk proteins as a consequence of adaptive divergence between the milks of mammalian speciespI values of all the orthologous proteins in human, mouse, and cow. The vertical and horizontal lines represents the neutral pH = 7. Most proteins have a similar pI between species, with some exceptions lying out on both sides of the diagonal. The red dots represent the three milk proteins that have the highest shift (κ-casein, lactadherin, and muc1).Back to article page
