1H, 13C and 15N resonance assignments and secondary structure of the human PHF6-ePHD1 domain.
The plant homeodomain (PHD) finger 6 (PHF6) is a multidomain protein that comprises four nuclear localization signals and two extended PHD zinc finger domains (ePHD), suggesting that the PHD domains of PHF6 may have different functions compared with other PHD domains. And the PHF6 was first identified as the gene mutated associated with Börjeson-Forssman-Lehmann syndrome, an X-linked mental retardation disorder. The mutant PHF6 is also associated with T cell acute lymphoblastic leukemia and acute myeloid leukemia. But the molecular mechanism between these diseases and PHF6 are still unclear. In addition, the first conserved ePHD (ePHD1) of PHF6 is involved in its nucleolus localization, directly interacts with upstream binding factor (UBF) and suppresses rRNA transcription. Here we show the backbone resonance and side chain assignments of the PHF6-ePHD1 domain from human by heteronuclear multidimensional NMR spectroscopy and its secondary structure as predicted by the TALOS+. These assignments of PHF6-ePHD1 domain throw a light on the further structure determination, dynamics and interaction with UBF.
