Summary: Enables protein phosphatase 2A binding activity. Involved in mitotic nuclear membrane reassembly and negative regulation of phosphorylation. Located in nuclear envelope. Human ortholog(s) of this gene implicated in primary autosomal recessive microcephaly 16. Orthologous to human ANKLE2 (ankyrin repeat and LEM domain containing 2).
