This presumed domain is found at the N-terminus of the S. cerevisiae Flo11 protein. Flo11 is required for diploid pseudohyphal formation and haploid invasive growth. It belongs to a family of proteins involved in invasive growth, cell-cell adhesion, and mating, many of which can substitute for each other under abnormal conditions [4].
