'''Flocculation protein''' or''' flocculin''' (FLO) are yeast adhesion protein family involved in cell-cell adhesion via lectin-carbohydrate interaction<ref>PMID:20640875</ref>. FLO1, FLO5, FLO9 and FLO10 have similar sequence and cause formation of cellular clumps (flocs) while FLO11 has unrelated sequence and is required for diploid formation and haploid invasive growth.

'''FLO1, FLO5, FLO9 and FLO10''' have similar sequence and cause formation of cellular clumps (flocs) while '''FLO11''' has unrelated sequence and is required for diploid formation and haploid invasive growth. Flocculins confer calcium-dependent cell-cell adhesion, formation of cellular flocs and protection against environmental stress.

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
The N-terminal domain of FLO is similar to the lectin-like domain of [[Adhesin]]. The Ca+2 ion binds to two carbohydrate-binding groups: a D''cis''D motif - 2 Asp residues connected with a ''cis'' bond and another β strand residues. The Ca+2 ion interacts with α-mannose which is an antiflocculant in vivo<ref>PMID:21149680</ref>. <scene name='91/919029/Cv/7'>α-mannose binding site</scene>.
