Summary
Predicted to enable protein kinase activity. Acts upstream of or within chromosome segregation and positive regulation of intrinsic apoptotic signaling pathway. Located in kinetochore. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in colorectal cancer. Orthologous to human BUB1 (BUB1 mitotic checkpoint serine/threonine kinase). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?
  1. Bub1 insufficiency attenuates TF expression and reduces TM suppression by blocking Akt and JNK phosphorylation, respectively, thus leading to the prevention of ARF and death caused by sepsis.
    Title: Budding Uninhibited by Benzimidazole-1 Insufficiency Prevents Acute Renal Failure in Severe Sepsis by Maintaining Anticoagulant Functions of Vascular Endothelial Cells.
  2. Bub1 coordinates checkpoint signalling by distinct domains for RZZ and BubR1 recruitment and localizes antagonistic checkpoint activities.
    Title: Distinct domains in Bub1 localize RZZ and BubR1 to kinetochores to regulate the checkpoint.
  3. It was shown that that Bub1 kinase activity integrates attachment error correction and mitotic checkpoint signaling by controlling the localization and activity of Aurora B kinase through phosphorylation of histone H2A at threonine 121.
    Title: Bub1 kinase activity drives error correction and mitotic checkpoint control but not tumor suppression.
  4. Results establish that Bub1 has oncogenic properties and suggest that Aurora B is a critical target through which overexpressed Bub1 drives aneuploidization and tumorigenesis.
    Title: Bub1 overexpression induces aneuploidy and tumor formation through Aurora B kinase hyperactivation.
  5. It seems that Sgo1 sets up the centromeric protection mechanism in G2, but that its Bub1-dependent localisation to centromeres during mitosis is not required to maintain cohesion.
    Title: Sgo1 establishes the centromeric cohesion protection mechanism in G2 before subsequent Bub1-dependent recruitment in mitosis.
  6. Bub1 insufficiency can drive tumor formation through tumor suppressor gene loss of heterozygosity, but only in restricted genetic and cellular contexts

  9. Bub1 is essential for proper chromosome segregation, a defect that can lead to severe phenotypes, including perinatal lethality and a predisposition to cancer.

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.
