The gene TTP, encoding a C3H zinc finger protein of the TIS11 family, is ex
pressed in growing mouse oocytes. The gene is downregulated in Graafian fol
licles shortly before ovulation. This corresponds to a possible function in
regulation of maternal mRNA translation, a function attributed to related
C3H class genes in Caenorhabditis elegans, zebrafish, and Xenopus.
