CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Lipid-anchor, GPI-
CC       anchor {ECO:0000305}.
CC   -!- PTM: The GPI-like-anchor contains a phosphoceramide group, rather than
CC       a phosphatidyl group. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the ponticulin family. {ECO:0000305}.
CC   -!- CAUTION: The Dictyosteliida are known to produce a
CC       glycosylsphingolipidinositol anchor (GPI-like-anchor). It has not been
CC       established whether Dictyosteliida make a glycosylphosphatidylinositol
CC       anchor (GPI-anchor) also, and whether their GPI-like-anchor
CC       modifications can be interconverted with GPI-anchor modifications in a
CC       resculpting process. It has not been established that the GPI-like-
CC       anchor modification in Dictyosteliida utilizes the same sequence motif.
CC       {ECO:0000305}.
CC   -!- CAUTION: Different sequence motifs predict both the N-glycosylation
CC       modification and the GPI- or GPI-like anchor modification for Asn-118.
CC       While it is chemically possible for both modifications to occur, it is
CC       not known whether it is enzymatically possible. {ECO:0000305}.
