Rif1 restrains the rate of replication origin firing in Xenopus laevis by Olivier Haccard, Diletta Ciardo, Hemalatha Narrissamprakash, Odile Bronchain, Akiko Kumagai, William G. Dunphy, Arach Goldar, Kathrin Marheineke

“…We have previously described that Rif1 depletion accelerates early Xenopus laevis embryonic cell cycles. Here, we find that in the absence of Rif1, patterns of replication foci change along with the acceleration of replication cluster activation. …”

Hybridization led to a rewired pluripotency network in the allotetraploid Xenopus laevis by Wesley A Phelps, Matthew D Hurton, Taylor N Ayers, Anne E Carlson, Joel C Rosenbaum, Miler T Lee

“…Here, we show that maternal homologs of mammalian pluripotency reprogramming factors OCT4 and SOX2 divergently activate the two subgenomes of Xenopus laevis, an allotetraploid that arose from hybridization of two diploid species ~18 million years ago. …”

Optogenetic dephosphorylation of phosphatidylinositol 4,5 bisphosphate in Xenopus laevis oocytes by Kirin D. Gada, Yu Xu, Brenda T. Winn, Meghan Masotti, Takeharu Kawano, Heikki Vaananen, Leigh D. Plant

“…Summary: Here, we present a protocol for optogenetic dephosphorylation of the phosphoinositide PI(4,5)P2 at the plasma membrane of Xenopus laevis oocytes. We first describe the co-injection of oocytes with cRNAs encoding (1) a light-activated PI(4,5)P2 5-phosphatase fusion protein, (2) its dimerization partner fused to the plasma membrane, and (3) the potassium channel reporter for PI(4,5)P2 dephosphorylation. …”
