Latherin (Surfactant Protein) + 6xHIS Tag

Latherin is a surfactant protein with detergent like properties. Its normal biological function is temperature regulation and is believed to function by enhancing evaporation from the pelt. It does so by binding to hydrophobic surfaces and allowing them to become wettable.

Applications

Latherin is able to temporarily bind to hydrophobic surfaces and has therefore been investigated as a possible method of breaking up biofilms. It is also suspected that the protein may have antimicrobial functions.
The 2011 University of Glasgow iGEM team used this part in their system, DISColi, to aid in the dispersal of biofilms.

Part:BBa_K660200

This is a version of the latherin biobrick (K660200) with an attached 6xHIS tag. Use this biobrick for affinity purification to isolate the protein.

Additional Information

Note: Latherin is suspected to be the cause of allergic reaction in individuals with an allergy to horses.
