Genes selected for testing in individual PBs and sibling oocytes

Gene	Function	Accession No.
BUB1	SAC proteins. Required for recruiting other SAC proteins to the kinetochore. Required for SAC in meiosis I and meiosis II.	NM_009772.2
CDC20	Binds to APC/C; interaction with the MCC inhibits APC/C activity.	NM_023223.2
Filia	Help maintain chromosome stability and euploidy in early-cleavage mouse embryogenesis. The depletion of Filia impairs preimplantation embryo development with a high incidence of aneuploidy	NM_025890.3
MCAK	Depolymerises microtubules in response to a lack of tension. Also required for poleward chromosome movement.	NM_134471.4
SGOL1	Shugoshin-like 1. Proteins that protects centromeric cohesion from phosphorylation during the prophase pathway and from separate during meiosis I.	NM_028232.2
SMC1A	Cohesin complex subunits protein during mitosis	NM_019710.2
