This entry represents the N-terminal Ig-like domain found in a family of serine- threonine-rich membrane-anchored proteins, anchored by glycosyl-phosphatidylinositol. This family includes Kre9. In A. fumigatus these proteins play a role in fungal cell wall organisation [2]. In Lentinula edodes this family is involved in fruiting body formation, and may have a more general role in signalling in other organisms as it interacts with MAPK [3]. The family is also found in archaea and bacteria.
