Acts as a transcriptional repressor. Inhibits erythroid differentiation and tumor cell proliferation. Plays a role during ovarian cancer development and progression.
Contributes to cervical carcinogenesis in part through the TNF-alpha-induced NF-kappa-B signaling pathway by interacting with the I-kappa-B-kinase (IKK) core complex.

Overexpressed in ovarian cancer tissues compared to normal ovarian tissues. Isoform 1 and isoform 2 are expressed in squamous epithelium tissues. Isoform 2 is overexpressed in squamous cervical cancer (at protein level). Expressed in blood cells. Isoform 1 is expressed in pancreas, lung, skeletal muscle, heart, placenta, liver, kidney and brain. Isoform 2 expressed in chronic lymphocytic leukemia (CLL) and several tumor cell lines. Isoform 3 is expressed in several tumor cells. Isoform 5 is expressed in fetal liver and several tumor cells. Isoform 6 is weakly expressed in brain, lung amd small intestin and in several tumor cells. Isoform 7 is expressed in fetal liver and several tumor cells.
