Analyses of meiotic progression
Investigation of cyclin B-CDK1 complex activity
Observation of chromosome segregation during oocyte meiosis
CKS-1 is identified as a critical component of the cyclin B-CDK1 complex
Proper chromosome segregation is dependent on CKS-1 activity
Disruption of CKS-1 function leads to meiotic errors

Resumen

Meiotic progression requires the activity of the cyclin B-CDK1 complex. In this issue, Yang et al. (https://doi.org/10.1083/jcb.202502087) demonstrate that the phospho-adaptor protein CKS-1 functions as a critical component of this complex to ensure proper chromosome segregation during oocyte meiosis.
