May be involved in transcriptional regulation. May be involved in regulation of cell proliferation. Expressed at high levels in the spleen, thymus, and PBMC, at low levels in the prostate, ovary, small intestine, colon (mucosal lining), placenta, lung, and pancreas, and very weakly expressed in the liver and kidney. Induced at the early stage of T cell activation. Regulated at the transcriptional level during the cell cycle. Induced at a maximum level in the S phase. Belongs to the krueppel C2H2-type zinc-finger protein family.
