Securin … Webthe metaphase to anaphase transition may lead to the premature separation of sister chromatids, prior to the establishment of bipolar spindle attachments. In this case, …
WebIn particular, the mutant cells have increased levels of Securin in pro-metaphase (PM) and decreased levels of Separase in anaphase (A), compared to the wild-type cells. This suggests that the mutation affects the regulation of the Metaphase-to-Anaphase transition by altering the levels or activity of these proteins.
