Enables DNA binding activity; histone acetyltransferase activity; and promoter-specific chromatin binding activity. Involved in histone acetylation. Located in pronucleus. Is expressed in several structures, including branchial arch; central nervous system; genitourinary system; hemolymphoid system gland; and sensory organ. Human ortholog(s) of this gene implicated in X-linked dystonia-parkinsonism and syndromic X-linked intellectual disability. Orthologous to several human genes including TAF1 (TATA-box binding protein associated factor 1). [provided by Alliance of Genome Resources, Apr 2022]
