Metabolic cost of osmoregulation in a hypertonic environment in the invasive African clawed frog Xenopus laevis
(Company of Biologists Ltd., 2016)
Studies of aquatic invertebrates reveal that salinity affects feeding and growth rates, reproduction, survival, and diversity. Little is known, however, about how salinity impacts the energy budget of vertebrates and ...
Characterization of protein synthesis initiation factor 2 from Xenopus laevis oocytes
(1988)
The protein synthesis initiation factor 2 (eIF2) from Xenopus laevis oocytes has been extensively purified and characterized. Depending upon the purification scheme, eIF2 containing three subunits (α, β and γ) with Mr of ...
Metabolismo del fosfatidilinositol-4-monofosfato en membranas aisladas de oocitos de xenopus laevis
(Universisdad de Chile, 1992)
El oocito de Xenopus laevis es una célula ampliamente
utilizada para el estudio de la transducción de señales
extracelulares puesto que posee receptores para acetilcolina,
progesterona e insulina y, ademas, la microinyeccion ...
Notch destabilises maternal β-catenin and restricts dorsal-anterior development in Xenopus
(Company of Biologists, 2011-06)
The blastula chordin- and noggin-expressing centre (BCNE) is the predecessor of the Spemann-Mangold's organiser and alsocontains the precursors of the brain. This signalling centre comprises animal-dorsal and marginal-dorsal ...
Ric-8A regulates neural crest cells induction in Xenopus tropicalis
(2014)
Introduction: The neural crest (NC) is a transient embryonic cell population that arises at the border of the neural plate during early development. Ric-8A, a guanine nucleotide exchange factor (GEF) over different Gα ...
Ric-8A/Galpha13 signaling pathway is required to proper cranial neural crest migration in Xenopus.
(2017)
Cell migration requires several signals to control cell movements, such as heterotrimeric
G protein pathway. Ric-8A, a GEF for Gα subunits plays an important role in neural
crest (NC) migration in Xenopus. However the Gα ...
Characterization of endogenous volume-sensitive ion currents and ATP release in Xenopus laevis oocytes
(Sociedad Argentina de Biofísica, 2019)
The Xenopus laevis oocyte is a well-known heterologous expression system. Several endogenous ion channels and transporters of Xenopus laevis oocytes have been well characterized, but the identification of volume-sensitive ...
Human-Xenopus chimeras of Gsα reveal a new region important for its activation of adenylyl cyclase
(1994)
G proteins are heterotrimeric GTPases that play a key role in signal transduction. The α subunit of Gs bound to GTP is capable of activating adenylyl cyclase. The amino acid sequences derived from two X. laevis cDNA clones ...
Clonamiento, secuenciación, expresión y estudio funcional de la subunidad B de la CK2 de xenopus laevis
(Universisdad de Chile, 1995)
La CK2 es una serina/treonina proteína quinasa que se encuentra
ampliamente distribuida tanto en el núcleo como en el citoplasma de
todas las células eucarioticas. Esta quinasa presenta una estructura
tetramerica y esta ...
