Specialization scoring - worked examples  
   
Example: Specialization in lactalbumin. After gene duplication 300 to 400 million years ago, an enzyme lysozyme C gave rise to a gene that currently codes for α-lactalbumin, a regulatory protein expressed only in the lactating mammary gland. Learn how to map the specialization info onto protein sequence and structure. Create excel spreadheets with specialization data, and specialization maps in png format.
