basic FUNCTION
  • mediating protein-protein interaction
  • essential for sperm flagellar motility and is important for the maintenance of the structural integrity of mature sperm
  • axoneme central apparatus protein, is essential for function of ependymal cell cilia and sperm flagella
  • SPAG6 not only regulates cilia/flagellar motility, but that in its absence, ciliogenesis, axoneme orientation, and tracheal epithelial cell polarity are altered
  • might have a role in malignant myeloid hematologic cell proliferation and apoptosis by regulating caspase proteins and TP53
  • plays an important role in sperm flagellar function
  • is crucial for sperm motility
  • likely controlled neuronal migration as well as neurite branching and elongation
  • selectively increased expression of acetylated tubulin, a microtubule stability marker
  • new roles for SPAG6 in modulation of cell morphology, proliferation, migration, and ciliogenesis
  • plays an essential role in the process of neuronal proliferation and differentiation
  • SPAG6 and L1TD1 are tumor-specifically methylated in non-small cell lung cancer (NSCLC) and DNA methylation is involved in the transcriptional regulation of these genes
  • potential role of SPAG6 and SPAG16 stabilizing the cytoplasmic microtubules of eukaryotic cells
  • SPAG6 gene regulates tumor cell proliferation, apoptosis, invasion, and metastasis
  • likely SPAG6 gene could affect hearing by regulating the expression of SLC26A5 gene
