Navs are subject to posttranslational modifications that may influence their cell membrane availability.

The abundance of histone H2A, H2B, H3, and H4 mRNAs is reduced to 37% to 70% of control levels in the SLBP knockdown cells when compared to the C2 control.

Up-regulation of skp2 by notch signaling enhances proteasome-mediated degradation of the ckis, p27 kip1 and p21 cip1, and causes premature entry into s phase. ;the recognition of p27 by skp2/cks1 of the scfskp2 complex is dictated by cycline/cdk2, providing a high affinity binding site and the phosphorylation of p27 at t187, serving here we provide evidence suggesting that both cdk2/e and phosphorylation of thr(187) on p27 are essential for the recognition of p27 by the scf(skp2/cks1) complex, the ubiquitin-protein isopeptide ligase (e3).
