Comments
N-truncated peroxisome proliferator-activated receptor gamma co-activator-1 alpha is composed of the first 270 amino acids of peroxisome proliferator-activated receptor co-activator-1. Note that the FASTA sequence is the full-length form. The truncated form has unique functionality as compared to the original protein in that it is relatively stable and predominantly found in the cytoplasm. cAMP, which also regulates PGC-1α, triggers the nuclear accumulation of NT-PGC-1α and enhances its recruitment to promoters of PGC-1α target genes. While NT-PGC-1α binds and is exported using CRM1, nuclear export of NT-PGC-1α is inhibited by PKA-dependent phosphorylation of Ser-194, Ser-241, and Thr-256. As could be suggested by nuclear accumulation, phosphorylation of NT-PGC-1α increases its transcriptional activity.

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.
