Using a combination of STRING analysis and DAVID functional classification, the FMRP N-tat associations in FXS neurons were generally like those observed in tsA-201 FMR1 KO cells, found to be associated with RNA stability, mRNA splicing, mitochondrial function, translation, and structural constituents of the ribosome (Fig. 5, B and C). Here, FMR1 is linked to fragile X syndrome.
