Journal Article

Sexual plasticity in fish: a possible target of endocrine disruptor action.

Yoshitaka Nagahama, +3 more
- 01 Jan 2004 - 
TL;DR: DMY is identified, for the first time in nonmammalian vertebrates, DMY, as the sex-determining gene of medaka, and sexual plasticity of gonads during sex differentiation may be implicated through the somatic cells within gonads.
Journal ArticleDOI

Isolation and characterization of goldfish cdk2, a cognate variant of the cell cycle regulator cdc2☆

Toshiaki Hirai, +6 more
- 01 Jul 1992 - 
TL;DR: The nucleotide and predicted amino acid sequences of the goldfish cdk2, a cognate variant of the cell cycle regulator cdc2, show strong homology to the other knowncdk2 and complex formation of cdk1 with a protein other than cyclins A or B is indicated.
Journal ArticleDOI

Possible function of caudal nuclear pocket : Degradation of nucleoproteins by ubiquitin-proteasome system in rat spermatids and human sperm

Celina M. Haraguchi, +6 more
- 20 Feb 2007 - 
TL;DR: It is suggested that pUP occur in the dense nuclear area of developing spermatids and that the ubiquitin-proteasome system is more actively operational in the nuclear pocket than dense area, which might be the degradation site for temporarily functioning proteins generating during condensation of chromatin in late sperMatids.
Book ChapterDOI

Nature and role of proteasomes in maturation of fish oocytes

Toshinobu Tokumoto
- 01 Jan 1999 - 
TL;DR: This review focuses on advances in the study of the biochemical properties and functions of the 20S and 26S proteasomes in the fish meiotic cell cycle.
Journal ArticleDOI

Characterization of multiple membrane progestin receptor (mPR) subtypes from the goldfish ovary and their roles in the induction of oocyte maturation.

Toshinobu Tokumoto, +16 more
- 15 May 2012 - 
TL;DR: Results suggest that the goldfish mPRβ protein acts as an intermediary during MIH induction of OM in goldfish, in a manner similar to that described previously for mPRα.
