Gene Summary
Serine/threonine-protein kinase that phosphorylates histone H3 at 'Thr-4' (H3T3ph) during mitosis and interphase (PubMed:32750047). Function is essential for chromosome organization during mitosis and genome organization in interphase cells, thus playing a functional role in gene regulation (PubMed:32750047). During mitosis, may act through H3T3ph to both position and modulate activation of AURKB and other components of the chromosomal passenger complex (CPC) at centromeres to ensure proper chromatid cohesion, metaphase alignment and normal progression through the cell cycle (By similarity). During interphase, associates with the cohesion complex and mediates pds5 binding to chromatin to ensure correct sister chromatid cohesion, chromatin organization, and also functions with Pds5-cohesin to modify Polycomb-dependent homeotic transformations (PubMed:32750047). Function during interphase is required for insulator activity, nuclear compaction, heterochromatin-induced position-effect variegation and PcG-mediated pairing-sensitive silencing (PubMed:32750047).

Summary (Interactive Fly)

a kinase that associates with the cohesin complex in interphase - mediates Pds5 binding to chromatin - cooperates with Pds5-cohesin to modify Polycomb-dependent homeotic transformations - asymmetric inheritance of centromeric proteins upon stem cell division - regulation of stem cell fate in asymmetric cell division - phosphorylation at threonine 3 of H3 distinguishes pre-existing versus newly synthesized H3 distinguishing sister chromatids enriched with distinct pools of H3 in order to coordinate asymmetric segregation of "old" H3 into GSCs - tight regulation of H3T3 phosphorylation is required for male germline activity

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
