Description

Predicted to enable 1-phosphatidylinositol 4-kinase activity. Acts upstream of or within inner ear morphogenesis and semicircular canal development. Predicted to be located in mitochondrial outer membrane and rough endoplasmic reticulum membrane. Predicted to be active in cytoplasm and membrane. Is expressed in brain; head; inner ear; pharyngeal arch 3-7; and semicircular canal. Orthologous to human PI4KB (phosphatidylinositol 4-kinase beta).
