Interleukin enhancer-binding factor 3 is aprotein that in humans is encoded by theILF3gene.[5][6]
Nuclear factor of activated T-cells (NFAT) is a transcription factor required for T-cell expression of interleukin 2. NFAT binds to a sequence in the IL2 enhancer known as the antigen receptor response element 2. In addition, NFAT can bind RNA and is an essential component forencapsidation and protein priming of hepatitis B viral polymerase. NFAT is a heterodimer of 45 kDa and 90 kDa proteins, the larger of which is the product of this gene. The encoded protein, which is primarily localized to ribosomes, probably regulates transcription at the level of mRNA elongation. At least three transcript variants encoding three different isoforms have been found for this gene.[7]
ILF3 has been shown tointeract with:
Small NF90/ILF3-associated RNAs (snaR) (~120 nucleotides long) and are known to interact with ILF3 double-stranded RNA-binding motifs.[17] snaR-A is abundant in human testis and has been shown to associate with ribosomes in HeLa cells. snaR-A is present in human and gorilla but not in chimpanzee. Other snaR RNAs are found in African Great Apes (including chimpanzee and bonobo).[18]
ILF2 and ILF3 have been identified as autoantigens in mice with induced lupus,[19][20] in canine systemic rheumatic autoimmune disease,[21] and as a rare finding in humans with autoimmune disease.[22]
