General Comment Nuclear factor of activated T cells (NFAT) is a transcription factor required for T-cell expression of interleukin 2 (IL2; OMIM 147680). NFAT binds to a sequence known as the antigen receptor response element 2 (ARRE2) in the IL2 enhancer. Purified NFAT contains 45- and 90-kD subunits.

NCBI Summary: Nuclear factor of activated T-cells (NFAT) is a transcription factor required for T-cell expression of the interleukin 2 gene. NFAT binds to a sequence in the interleukin 2 gene enhancer known as the antigen receptor response element 2. In addition, NFAT can bind RNA and is an essential component for encapsidation and protein priming of hepatitis B viral polymerase. NFAT is a heterodimer of 45 kDa and 90 kDa proteins, the smaller of which is the product of this gene. The encoded protein binds strongly to the 90 kDa protein and stimulates its ability to enhance gene expression.

Ovarian localization Oocyte
Comment Lopez-Fernandez LA, et al reported that Ilf2 is regulated during meiosis and associated to transcriptionally active chromatin. Analysis of gene expression during testis development demonstrated accumulation of Ilf2 mRNA in pachytene spermatocytes. In these cells, the protein was localized in the nucleus, but it was absent from chromatin of the XY pachytene bivalent, in which there is no transcriptional activity. Nucleolar signal is inmmunolocalized in spermatogonia, Sertoli cells and oocytes. By in situ hybridisation, Ilf2 expression is detected in proliferative cells of adult ovary and a defined pattern is also exhibited in different tissues of embryos. The presence of ILF2 in active chromatin is corroborated in NIH3T3 cultured cells after transfection with Ilf2-EGFP constructs.
