High impact information on sra

  • Eggs laid by sarah mutant females arrest in anaphase of meiosis I and fail to fully polyadenylate and translate bicoid mRNA [1].
  • Furthermore, sarah mutant eggs show elevated cyclin B levels, indicating a failure to inactivate M-phase promoting factor (MPF) [1].
  • Taken together, these results demonstrate that calcium signaling is involved in Drosophila egg activation and suggest a molecular mechanism for the sarah phenotype [1].
  • The calcineurin regulator sra plays an essential role in female meiosis in Drosophila [2].
  • Here, we show that the Drosophila MCIP sarah (sra) is essential for meiotic progression in oocytes [2].
 

Biological context of sra

  • This phenotype was due to loss of function of sra specifically in the female germline [2].
  • Eggs from sra null mothers are arrested at anaphase of meiosis I [2].
  • Taken together, these results indicate that the expression level of sra is critical for ovulation and female courtship behavior, including their postmating changes [3].
