Comments
NF-ATc1 is one of the four members of the nuclear factor of activated T (NFAT) cells gene family involved in the activation of early response genes. The activity of NFATc is controlled by Ca2+-calcineurin. In resting cells, the N-terminus of NFATc is located in the cytoplasm and phosphrylated at multiple serines. In response to Ca2+ signals, the dephosphorylation by calcineurin unmasked the NLS in NFACT, resulting in nuclear accumulation of NFACT. Upon termination of Ca2+ signaling, NFACT exits the nucleus rapidly, supposedly through CRM1-dependent pathway. Note that overexpression of GSK3, which phosphorylates the serines can enhance NFATc export. On the other hand, lithium, which inhibits GSK3 activity, can reduce export.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
