    text
  • localized to interphase nucleus and mitotic chromosomes
  • in interphase cells, SPIN1 specifically localizes to the nucleoli, and localizes to the active ribosomal DNA (rDNA) repeats, facilitating the expression of rRNA genes 6)
  • basic FUNCTION
  • playing a role in cell-cycle regulation during the transition from gamete to embryo
  • important gene for mitotic chromosome functions, and its disrupted regulation results in abnormal cell division, a mechanism that may be involved in tumorigenesis
  • meiotic spindle-binding protein, involved in gametogenesis
  • target for cell cycle-dependent phosphorylation and disturb the cell cycle
  • is an important gene for mammalian mitotic chromosome functions, and disrupted regulation results in abnormal cell division, a mechanism that may be involved in tumorigenesis
  • meiotic spindle-associated protein
  • is a histone methylation effector protein that specifically recognizes H3K4 methylation
  • involved in the process of spindle organization and chromosomal stability and plays a role in the development of cancer
  • regulates maternal transcripts post-transcriptionally and is involved in meiotic resumption
  • histone effector that senses a cis-tail histone H3 methylation pattern involving trimethyllysine 4 (H3K4me3) and asymmetric dimethylarginine 8 (H3R8me2a) marks
  • is a transcriptional coactivator with critical functions in embryonic development and emerging roles in cancer
  • regulates gene expression in the Wnt signaling pathway by directly interacting with transcription factor 4 (TCF4)
  • histone code reader SPIN1 controls skeletal muscle development
  • CELLULAR PROCESS cell cycle
    PHYSIOLOGICAL PROCESS development
    text
  • early embryogenesis
  • cell-cycle regulation
  • PATHWAY
    metabolism
    signaling
    a component
  • SPIN1, via its Tudor-like domain, forms a ribonucleoprotein complex with SERBP1, and regulating mRNA stability and/or translation
  • INTERACTION
    DNA
    RNA
    small molecule other,
  • associations with nucleic acid to provide a biochemical basis for its cell cycle regulation and other functions
  • AURKA could interact with and phosphorylate SPIN1 at its key functional sites, Ser84 and Ser99, suggesting that phosphorylation of SPIN1 is involved in its oncogenic function
  • SPIN1, a maternal protein containing Tudor-like domains, interacts with a known mRNA-binding protein SERBP1, and is involved in regulating maternal transcripts to control meiotic resumption
  • SPIN1 directly enhances expression of GDNF, an activator of the RET signaling pathway, in cooperation with the transcription factor MAZ
  • SPINDOC directly binds SPIN1 and strongly disrupts its histone methylation reading ability, causing it to disassociate from chromatin
  • SPINDOC is a transcriptional repressor that binds SPIN1 and masks its ability to engage the H3-Lys-4 trimethylation activation mark
  • SPIN1 is required for the association or assembly of selective factor 1 (TAF1C) complex, probably facilitating the initiation of rDNA transcription
