mosaic protein

mosaic protein

Any of the functionally diverse proteins that have evolved by duplication, insertion and deletion of a common pool of structural units or modules—defined as consensus sequences containing conserved disulfide bonds. Mosaic proteins are involved in cell adhesion, migrations and embryogenesis, as well as in the coagulation, fibrinolytic and complement pathways.
 
Examples
Fibronectin, coagulation factor XII, tPA.

A novel mosaic protein containing LDL receptor elements is highly conserved in humans and chickens.
Our findings also lend support to the concept that the LDL receptor is a mosaic protein whose gene is built up of exons that have been borrowed from or loaned to other genes and is thus a member of several supergene families.
