Predicted to enable glycerophosphocholine phosphodiesterase activity. Predicted to be involved in positive regulation of cell cycle. Predicted to act upstream of or within several processes, including negative regulation of Notch signaling pathway; neuron differentiation; and regulation of timing of cell differentiation. Predicted to be located in several cellular components, including axon; neuronal cell body; and perinuclear endoplasmic reticulum. Orthologous to human GDPD5 (glycerophosphodiester phosphodiesterase domain containing 5). [provided by Alliance of Genome Resources, Apr 2022]
