Predicted to enable DNA binding activity; methylated histone binding activity; and phosphatidylinositol binding activity. Involved in several processes, including male gamete generation; positive regulation of histone deacetylation; and seminiferous tubule development. Acts upstream of or within negative regulation of apoptotic signaling pathway and positive regulation of transcription, DNA-templated. Predicted to be located in nucleoplasm and plasma membrane. Predicted to be part of CCAAT-binding activity factor complex and Sin3 complex. Predicted to be active in nucleus. Is expressed in several structures, including alimentary system; brain; branchial arch; genitourinary system; and immune system. Orthologous to human ING2 (inhibitor of growth family member 2).
