Summary: Enables chromatin DNA binding activity and histone acetyltransferase binding activity. Involved in several processes, including regulation of gene expression; regulation of mitotic nuclear division; and spindle organization. Located in several cellular components, including euchromatin; nucleus; and spindle. Part of nuclear pore. Is expressed in adult brain cell body rind; adult head; adult optic lobe; male germline cell; and somatic cell of testis. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder. Orthologous to human TPR (translocated promoter region, nuclear basket protein).
