Enables protein domain specific binding activity and protein phosphatase binding activity. Acts upstream of or within several processes, including negative regulation of protein dephosphorylation; neuron migration; and pallium development. Located in cytoplasm. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Used to study Miller-Dieker lissencephaly syndrome and left ventricular noncompaction. Orthologous to human YWHAE (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein epsilon).
