AtUTr2 is an Arabidopsis thaliana nucleotide sugar transporter located in the Golgi apparatus capable of transporting UDP-galactose
(2005)
The synthesis of noncellulosic polysaccharides and glycoproteins in the plant cell Golgi apparatus requires UDP-galactose as a substrate. We have cloned and characterized a nucleotide sugar transporter from Arabidopsis ...
HUMAN PLACENTAL ATP-DIPHOSPHOHYDROLASE - BIOCHEMICAL .CHARACTERIZATION, REGULATION AND FUNCTION
(PERGAMON-ELSEVIER SCIENCE LTD, 1994-03)
1. Kinetic and physico-chemical studies on human placental microsomal fraction confirmed that the ATPase and ADPase activities detected in this fraction correspond to the enzyme ATP-diphosphohydrolase or apyrase (EC 3.6.1.5). ...
Changes in apyrase activity in uterus and mammary gland during the lactogenic cycle
(1992)
1. 1. The purpose of this present research was to explore the possible roles of ATP-diphosphohydrolase (apyrase) in two tissues with high energetic demands during cell proliferation and differentiation. 2. 2. Changes in ...
Round‐Headed Spermatozoa: A Model to study the Role of the Acrosome in early events of Gamete Interaction: Rundkopfspermatozoen: Ein Modell zum Studium der Rolle des Akrosoms
(1990)
Summary: Gamete interactions in mouse involves at least two steps: the first is the interaction of a spermatozoa receptor located in the plasma membrane and ZP3, a zona pellucida (ZP) glycoprotein. ZP3 also can induce the ...
Concholepas hemocyanin biosynthesis takes place in the hepatopancreas, with hemocytes being involved in its metabolism
(2010)
Hemocyanins are copper-containing glycoproteins in some molluscs and arthropods, and their bestknown function is O2 transport. We studied the site of their biosynthesis in the gastropod Concholepas concholepas by using ...
Interfering of the Reelin/ApoER2/PSD95 Signaling Axis Reactivates Dendritogenesis of Mature Hippocampal Neurons
(Wiley-Liss Inc., 2017)
© 2016 Wiley Periodicals, Inc. Reelin, an extracellular glycoprotein secreted in embryonic and adult brain, participates in neuronal migration and neuronal plasticity. Extensive evidence shows that reelin via activation ...
Hemocyanins as immunostimulants Hemocianinas, una herramienta inmunológica de la biomedicina actual
(2011)
Hemocyanins, the giant oxygen transporter glycoproteins of diverse mollusks, are xenogenic to the mammalian immune system and they display a remarkable immunogenicity. Therefore they are ideal non-specific immunostimulants ...
A mechanistic approach for the optimization of loperamide loaded nanocarriers characterization: Diafiltration and mathematical modeling advantages
(Elsevier B.V., 2018)
© 2018 Elsevier B.V. Oral bioavailability of loperamide is restricted by its limited absorption in the gastrointestinal tract due to its poor aqueous solubility and its P-glycoprotein (Pgp) substrate characteristic. In ...
Overexpression of amyloid precursor protein increases copper content in HEK293 cells
(2009)
Amyloid precursor protein (APP) is a transmembrane glycoprotein widely expressed in mammalian tissues and plays a central role in Alzheimer's disease. However, its physiological function remains elusive. Cu2+ binding and ...
Expression of multidrug resistance proteins in prostate cancer is related with cell sensitivity to chemotherapeutic drugs
(2009)
BACKGROUND. Multidrug resistance (MDR) proteins have been associated with the lack of chemotherapy response. Expression of these proteins has been described in the prostate, but there is no information about their role in ...
