Predicted to enable phosphatidylinositol deacylase activity. Acts upstream of or within embryonic pattern specification; regionalization; and sensory perception of sound. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be active in endoplasmic reticulum. Is expressed in several structures, including brain; genitourinary system; and neural ectoderm. Used to study holoprosencephaly. Orthologous to human PGAP1 (post-GPI attachment to proteins inositol deacylase 1). [provided by Alliance of Genome Resources, Apr 2022]
