    Title: M-phase phosphoprotein 8 promotes gastric cancer growth and metastasis via p53/Bcl-2 and EMT-related signaling pathways.
  2. The study demonstrated that MPP8 was associated with non-small cell lung cancer cell proliferation through regulation of HOXA5.
    Title: Knockdown of MPP8 suppresses cell proliferation via regulation of HOXA5 in non-small cell lung cancer cells.
  3. The haploid screen identified HUSH, an epigenetic heterochromatin repressor complex composed of three subunits, TASOR, MPP8 and Periphilin. (Review)
    Title: Position-effect variegation revisited: HUSHing up heterochromatin in human cells.
  4. findings demonstrate MPP8 and SIRT1 reciprocally regulate each other's function at multiple molecular layers through physical interaction; disruption of MPP8-SIRT1 interaction de-represses E cadherin expression and reduces cell motility and invasiveness suggesting this interplay plays critical role in MPP8- and SIRT1-mediated epithelial-mesenchymal transition
    Title: MPP8 and SIRT1 crosstalk in E-cadherin gene silencing and epithelial-mesenchymal transition.
  5. this study identified the HUSH (human silencing hub) complex, comprising three poorly characterized proteins, TASOR, MPP8, and periphilin; this complex is absent from Drosophila but is conserved from fish to humans.
    Title: GENE SILENCING. Epigenetic silencing by the HUSH complex mediates position-effect variegation in human cells.
  6. Knockdown analysis of MPP8 in HeLa cells resulted in derepression of a set of genes that are normally expressed in spermatogonia, spermatids and mature sperm, thereby indicating a role for this molecule in silencing testis-related genes in somatic cells.
    Title: Physical interaction between MPP8 and PRC1 complex and its implication for regulation of spermatogenesis.
  7. interaction of HN with MPP8 may play a role in oncogenesis because MPP8 increases tumor cell motility and invasion
    Title: Humanin binds MPP8: mapping interaction sites of the peptide and protein.
  8. these results indicate that the chromatin association of MPP8 is regulated by Cdk-dependent phosphorylation.

  10. We determined the crystal structure of MPP8 chromodomain in complex with H3K9me3 peptide. MPP8 interacts with at least six histone H3 residues from glutamine 5 to serine 10.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
