The haemoglobins of Xenopus laevis have been studied by carboxymethyl-cellulose column chromatography and by polyacrylamide gel disk electrophoresis. In Xenopus tadpoles, 2 haemoglobins are found (Xenopus-HbFx and Xenopus-HbF^). Both haemoglobins persist throughout tadpole life: Xenopus-HbF\ is the main tadpole haemoglobin; Xenopus-HbFt is present in rather smaller amounts. The proportion of Xe...

Abstract The S362A mutation block ROMK2 (Kir1.1b) endocytosis in Xenopus laevis oocyte membrane . Saeed Hajihashemi1 , 1-Assistant professor, PhD in Physiology, Department of Physiology, School of Medical science, Arak University of Medical Sciences. Introduction: ROMK channel is localized on the apical membrane of the nephron. Recent studies suggest that endocytosis of ROMK chan...

The western clawed frog Xenopus tropicalis is an important model for vertebrate development that combines experimental advantages of the African clawed frog Xenopus laevis with more tractable genetics. Here we present a draft genome sequence assembly of X. tropicalis. This genome encodes more than 20,000 protein-coding genes, including orthologs of at least 1700 human disease genes. Over 1 mill...

Here we report the purification, from Xenopus laevis oocyte nuclear extracts, of a new endoribonuclease, XendoU, that is involved in the processing of the intron-encoded box C/D U16 small nucleolar RNA (snoRNA) from its host pre-mRNA. Such an activity has never been reported before and has several uncommon features that make it quite a novel enzyme: it is poly(U)-specific, it requires Mn(2+) io...

Xenopus laevis has been used for many decades to study oocyte development and maturation. The Xenopus oocytes' large size, relative abundance, and clearly defined progression of physical characteristics from oogonia to eggs make them ideal for studying oogenesis. In addition, the ability of steroids to trigger Xenopus oocyte maturation in vitro has resulted in their extensive use for the study ...
