Zfp207-flox Mouse

Zfp207, a zinc finger protein, is essential for mammalian embryonic development [1]. It is involved in multiple biological processes such as maintaining pluripotency in mouse embryonic stem cells (ESCs), coordinating meiotic chromosome alignment in mouse oocytes, and regulating spliceosome assembly [1,2,3]. In plants, it acts as a transcriptional repressor of the green revolution gene SD1/OsGA20ox2 in rice, influencing plant growth and development [4].

In mouse models, silencing of Zfp207 in ESCs leads to severe neuroectodermal differentiation defects, highlighting its role in ESC maintenance [1]. Depletion of Zfp207 in mouse oocytes results in impaired spindle organization, misaligned chromosomes, defective kinetochore-microtubule attachments, and increased aneuploid metaphase II eggs, indicating its importance in meiotic chromosome alignment and spindle assembly checkpoint (SAC) function [2]. Aging-related aneuploidy in mouse oocytes is associated with changes in Zfp207 expression, suggesting its link to mitochondrial imbalance and spindle assembly failure [5].

In conclusion, Zfp207 plays crucial roles in maintaining cell pluripotency, regulating meiotic processes in oocytes, and influencing plant growth. Mouse gene knockout or knockdown models have been instrumental in revealing these functions, providing insights into developmental processes and potential implications in aneuploid-related conditions [1,2,5].
