Immunofluorescence analysis of Phospho-NFAT1 pSer54 was done on 70% confluent log phase HeLa cells treated with 200nM of PMA for 20 minutes. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with phospho-NFAT1 pSer54 Rabbit Polyclonal Antibody (44944G) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing cytoplasmic and nuclear localization. Panel e is untreated cells with no signal. Panel f is no primary antibody control. The images were captured at 60X magnification.

The nuclear factor of activated T-cells (NFAT) transcription complex is required for the expression of a group of proteins that collectively regulate the immune response. Four NFAT proteins, encoded on separate genes and expressed as several splice variants, have been described: NFAT1 (also known as NFATp or NFATc2), NFAT2 (NFATc or NFATc1), NFAT3, and NFAT4 (NFATx or NFATc3). These proteins show a low level of sequence similarity with the Dorsal/Rel/NFkB family of transcription factors. Another NFAT-related protein termed NFAT5 differs from isoforms 1-4 in that it lacks many of the Fos/Jun contact sites observed in its predecessors and its subcellular localization is not calcineurin-dependent.
