Summary: This gene encodes a component of the mitotic spindle assembly complex. The encoded protein is involved in the regulation of chromosome segregation during oocyte meiosis. Disruption of this gene results in the accumulation of mitotic errors and is lethal in the embryonic stage. Alternative splicing results in multiple transcript variants.

Data show that Zfp207 binds to Bub3 to form a complex and maintains its protein level in oocytes, and that overexpression of Bub3 is able to partially rescue the occurrence of aneuploid eggs in Zfp207-depleted oocytes.
Title: Zfp207 is a Bub3 binding protein regulating meiotic chromosome alignment in mouse oocytes.
as a member of the spindle assembly checkpoint, Bub3 is required for regulation of both meiosis I and II, and is potentially involved in kinetochore-microtubule attachment in mammalian oocytes
Title: Bub3 is a spindle assembly checkpoint protein regulating chromosome segregation during mouse oocyte meiosis.
Cenpa, Cenpb, and Bub3, but not Cenpc, interacted with PARP-1
Title: Centromere proteins Cenpa, Cenpb, and Bub3 interact with poly(ADP-ribose) polymerase-1 protein and are poly(ADP-ribosyl)ated.
Haploinsufficiency of Bub3 causes a slight increase in chromosome instability but is not clearly associated with a noticeable rise in the probability of tumor formation.
Title: Increased chromosome instability but not cancer predisposition in haploinsufficient Bub3 mice.
subpopulation of dynein, containing the DYNLT3 light chain, may be important for chromosome congression, in addition to having a role in the transport of checkpoint proteins from the kinetochore to the spindle pole
Title: The DYNLT3 light chain directly links cytoplasmic dynein to a spindle checkpoint protein, Bub3.

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.
