GLEYA domain The GLEYA domain is related to lectin-like binding domains found in the S. cerevisiae Flo proteins and the C. glabrata Epa proteins. It is a carbohydrate-binding domain that is found in fungal adhesins (also referred to as agglutinins or flocculins). Adhesins with a GLEYA domain possess a typical N-terminal signal peptide and a domain of conserved sequence repeats, but lack glycosylphosphatidylinositol (GPI) anchor attachment signals. They contain a conserved motif G(M/L)(E/A/N/Q)YA, hence the name GLEYA. Based on sequence homology, it is suggested that the GLEYA domain would predominantly contain beta sheets. The GLEYA domain is also found in S. pombe protein Swiss:Q92344, thought to be a kinetochore portein (Sim4 complex subunit), however no direct evidence for kinetochore association has been found. Furthermore, a global protein localization study in S. pombe identified it as a secreted protein localized to the Golgi complex. |
