Caf1-His protein

What is it?

For our project, we applied polyhistidine tags to capsular antigen fragments 1 (Caf1). This protein attaches to other Caf1-His proteins as well as other caf1 network proteins like Capsular antigen fragment 1-Antimicrobial peptides (BBa_K4897007) through the property of Caf1 in its ability to form polymers under cool conditions, contrasting from the monomer form of the protein when heated. Through his-tag antibodies, individual his-tags are connected together from separate polymers, forming a net shape. Moreover, protein A/G can be attached to his-tag antibodies. Subsequently, protein A/G magnetic beads can attach to the protein A/G’s, allowing the removal of Caf1 as a whole using a magnet.

Usage and Biology

By forming a net structure with his-tag antibodies, the caf1 proteins trap P. acne ahead of time before initiating inhibition of the bacteria. Moreover, the interaction with protein A/G assists with the removal of the P. acne as well as the protein post-inhibition.
