The protease degrading sperm histones post-fertilization in sea urchin eggs is a nuclear cathepsin L that is further required for embryo development.

Proteolysis of sperm histones in the sea urchin male pronucleus is the consequence of the activation at fertilization of a maternal cysteine protease. We previously showed that this protein is required for male chromatin remodelling and for cell-cycl

We have previously reported that sperm histones (SpH) degradation after fertilization is catalyzed by a cystein-protease (SpH-protease). Its inhibition blocks the degradation of SpH in vivo and also aborts sea urchin development at the initial embryo

Male pronucleus formation involves sperm nucleus decondensation and sperm chromatin remodeling. In sea urchins, male pronucleus decondensation was shown to be modulated by protein kinase C and a cdc2-like kinase sensitive to olomoucine in vitro assay

Functional studies of MP62 during male chromatin decondensation in sea urchins

Autor: Marcia Puchi, Viviana E. Hermosilla, Violeta Morin, Claudio Iribarren

Publikováno v: Journal of cellular biochemistry. 114(8)

In amphibians, sperm histone transition post-fertilization during male pronucleus formation is commanded by histone chaperone Nucleoplasmin (NPM). Here, we report the first studies to analyze the participation of a Nucleoplasmin-like protein on male

We had previously reported that a cysteine-protease catalyzes the sperm histones (SpH) degradation associated to male chromatin remodeling in sea urchins. We found that this protease selectively degraded the SpH leaving maternal cleavage stage (CS) h

Nuclear cysteine-protease involved in male chromatin remodeling after fertilization is ubiquitously distributed during sea urchin development

Publikováno v: Journal of cellular biochemistry. 101(1)

Previously we have identified a cysteine-protease involved in male chromatin remodeling which segregates into the nuclei of the two blastomeres at the first cleavage division. Here we have investigated the fate of this protease during early embryogen

We reported recently that the inhibition of cysteine-proteases with E-64-d disturbs DNA replication and prevents mitosis of the early sea urchin embryo. Since E-64-d is a rather general inhibitor of thiol-proteases, to specifically target the cystein
