FLO11/YIR019C Summary Help

Standard Name FLO11 1
Systematic Name YIR019C
Alias STA4 , MUC1 2
Feature Type ORF, Verified
Description GPI-anchored cell surface glycoprotein (flocculin); required for pseudohyphal formation, invasive growth, flocculation, and biofilms; transcriptionally regulated by the MAPK pathway (via Ste12p and Tec1p) and the cAMP pathway (via Flo8p); required for formation of fibrous interconnections between cells in a colony of a wild S. cerevisiae strain; a portion is cleaved and shed from cells, and free extracellular Flo11p contributes to the surface properties of cells (2, 3, 4, 5, 6, 7)
