Involved in the sexual cell fusion of D.discoideum. Expressed at the time of acquisition of fusion competence of cells. The sugar chains may play important roles in cell fusion. The GPI-like-anchor contains a phosphoceramide group, rather than a phosphatidyl group. The Dictyosteliida are known to produce a glycosylsphingolipidinositol anchor (GPI-like-anchor). It has not been established whether Dictyosteliida make a glycosylphosphatidylinositol anchor (GPI-anchor) also, and whether their GPI-like-anchor modifications can be interconverted with GPI-anchor modifications in a resculpting process. It has not been established that the GPI-like-anchor modification in Dictyosteliida utilizes the same sequence motif.
