Enables histone acetyltransferase activity. Acts upstream of or within cellular response to leukemia inhibitory factor and histone acetylation. Predicted to be located in nucleus. Predicted to be part of MOZ/MORF histone acetyltransferase complex. Is expressed in several structures, including brain; early conceptus; facial prominence; genitourinary system; and limb mesenchyme. Used to study Noonan syndrome. Human ortholog(s) of this gene implicated in bipolar disorder; blepharophimosis-intellectual disability syndrome, SBBYS type; breast cancer; and leiomyoma. Orthologous to human KAT6B (lysine acetyltransferase 6B). [provided by Alliance of Genome Resources, Apr 2022]
