Cell-cell adhesion during development. Attached to the membrane by a GPI-like-anchor that contains a phosphoceramide group. Expressed in vegetative cells and throughout development. Levels peak during the aggregation stage before declining and then rising again during culmination (at protein level). Contains 18 disulfide bonds. The GPI-like-anchor contains a phosphoceramide group, rather than a phosphatidyl group. Loss-of-function mutant (antisense inhibition) shows reduced cell adhesiveness and forms smaller aggregates than wild-type, though it does complete development and produce fruiting bodies. 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), 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 as the GPI-anchor modification.
