May bind F-actin and nucleates actin assembly. Appears first in the multicellular stage soon after tip formation and is selectively expressed on prespore cells. O-glycosylated in the repeat region. The oligosaccharides contain N-acetylglucosamine and fucose as the major constituents. The GPI-like-anchor contains a phosphoceramide group, rather than a phosphatidyl group. Allelic variation results in a protein with three, four or five tandem copies of Pro-Thr-Val-thr. Belongs to the ponticulin family. 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.
