  • N-terminal WD40 domain
  • one HMG-box
  • seven WD40 repeats
  • a SepB domain likely playing a primary role determining the dimeric structure , in the middle
  • C-terminal HMG motif
    interspecies ortholog to murineWdhd1
    CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
  • in nucleoplasm during interphase and translocated in cytoplasm during mitosis
  • associates with centromeres in a cell cycle-dependent manner, coinciding with mid-to-late S phase
  • associates with chromatin at late mitosis, suggesting that WDHD1 may be involved in the assembly of newly synthesized CENPA in early G1 phase
  • basic FUNCTION
  • transferase activity
  • may be involved in chromatin assembly, transcription and replication
  • coordinating multiple cellular events in S phase and G(2) phase such as DNA replication, checkpoint activation, sister chromatid cohesion, and DNA damage repais, thus playing a pivotal role in the maintenance of genome integrity
  • with ATAD5, and CHTF18 may coordinate the relative movement of the replication fork with respect to the cohesin ring
  • is likely to play an important role in lung and esophageal carcinogenesis as a cell cycle regulator and a downstream molecule in the phosphoinositide 3-kinase/AKT pathway
  • required for both DNA replication and the establishment of sister chromatid cohesion
  • plays an essential role in DNA replication and its ability to stimulate the replicative DNA polymerases may contribute to this effect
  • key regulator of centromere function
  • may be a critical component of the RNA-dependent epigenetic control mechanism that sustains centromere integrity and genomic stability
  • assembled onto chromatin in late mitosis and early G(1) phase before the assembly of prereplicative (pre-RC)complex in cells
  • facilitates loading of the MCM2-7 helicase onto chromatin during the assembly of pre-RC
  • is an important factor that functions together with HJURP to facilitate the cell cycle-specific recruitment of CENPA to centromeres
  • is required for the centromere-specific deposition of new CENPA in early G1 phase
  • CELLULAR PROCESS nucleotide, transcription, regulation
    metabolism carbohydrate
    a component
  • forms complexes with MCM2-7 to facilitate the assembly of MCM2-7 onto chromatin at replication origins in late mitosis and G(1) phase
  • forms a complex with prenucleosomal CENPA
  • WDHD1-CLSPN-TIPIN-TIMELESS complex, which coordinate DNA unwinding with polymerase alpha-, delta-, and epsilon- dependent DNA polymerization are constituents of the Replisome
    DNA binding
    small molecule
  • interacts with MCM10, which associates with MCM2-7, and with the p180 subunit of POLA
  • high mobility group domain-containing protein having remarkable capability to regulate the stability of KAT2A proteins and thereby histone H3 acetylation
  • functional link between KAT2A and WDHD1 essential for KAT2B protein stability and histone H3 acetylation, but also a potential role of WDHD1 in cancer
  • DTL and WDHD1 play an essential role in the regulation of KAT2A protein stability
  • DNA2 associates with the replisome protein WDHD1 in a cell cycle-dependent manner
  • is a new factor that is required for the assembly of CENPA nucleosomes
  • HJURP-interacting partner required for HJURP localization at centromeres
  • interacts with both CENPA and HJURP in a prenucleosomal complex, and the association of WDHD1 with CENPA is increased during the cell cycle transition from mitosis to G1 phase
