Nuclear translocation of ATG5 induces DNA mismatch repair deficiency (MMR-D)/microsatellite instability (MSI) via interacting with Mis18alpha in colorectal cancer.
Title: Nuclear translocation of ATG5 induces DNA mismatch repair deficiency (MMR-D)/microsatellite instability (MSI) via interacting with Mis18α in colorectal cancer.
Data show that the MIS18 kinetochore protein A (Mis18alpha) N-terminal region modulates Holliday junction recognition protein (HJURP) binding.
Title: Mechanism of centromere recruitment of the CENP-A chaperone HJURP and its implications for centromere licensing.
The authors demonstrate that CDK1 controls Mis18 complex recruitment to centromeres by regulating oligomerization of M18BP1 through the Mis18alpha:Mis18beta scaffold.
Title: CDK-regulated dimerization of M18BP1 on a Mis18 hexamer is necessary for CENP-A loading.
the Mis18 complex contains dual CENP-C recognition motifs that are combinatorially required to generate robust centromeric localization that leads to CENP-A deposition
Title: Differential Binding Partners of the Mis18α/β YIPPEE Domains Regulate Mis18 Complex Recruitment to Centromeres.
Mis18alpha is important for epidermal cell proliferation and stratification, because it is required for the deposition of CENP-A at the centromeric nucleosomes.
Title: Skin-Specific Deletion of Mis18α Impedes Proliferation and Stratification of Epidermal Keratinocytes.
Stable binding of Mis18alpha-Mis18beta heterotetramer to centromeres in telophase licenses them for CENP-A deposition.

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.
