Glycerophosphodiester phosphodiesterase that promotes cell cycle exit and drives spinal motor neuron differentiation (PubMed:16195461, PubMed:19766572, PubMed:23329048). Mediates the cleavage of glycosylphosphatidylinositol (GPI) anchor of target proteins: removes the GPI-anchor of RECK, leading to release RECK from the plasma membrane (PubMed:23329048). May contribute to the osmotic regulation of cellular glycerophosphocholine (By similarity). {By
