Human sperm subpopulations: relationship between functional quality and protein tyrosine phosphorylation
(European Society of Human Reproduction and Embriology, 2004-12)
Human semen is composed of a heterogeneous population of sperm with varying degrees of structural and functional differentiation and normality, which result in subpopulations of different quality.
Using a discontinuous ...
An ACTH-activated protein tyrosine phosphatase (PTP) is modulated by PKA-mediated phosphorylation
(Taylor, 2000-11)
In adrenal cortex, ACTH regulation of steroidogenesis depends on PKA-dependent serine/threonine phosphorylation and also on the activity of protein tyrosine phosphatases (PTPs). In addition, ACTH increases total PTPs ...
Increased tyrosine phosphorylation of band 3 in hemoglobinopathies
(Wiley-lissNew YorkEUA, 1998)
Insulin induces tyrosine phosphorylation of Shc and stimulates Shc/GRB2 association in insulin-sensitive tissues of the intact rat
(Humana Press IncTotowaEUA, 1998)
Role of Protein Phosphorylation and Tyrosine Phosphatases in the Adrenal Regulation of Steroid Synthesis and Mitochondrial Function
(Frontiers, 2016-06)
In adrenocortical cells, adrenocorticotropin (ACTH) promotes the activation of several protein kinases. The action of these kinases is linked to steroid production, mainly through steroidogenic acute regulatory protein ...
Nitric oxide and cGMP activate the Ras-MAP kinase pathway-stimulating protein tyrosine phosphorylation in rabbit aortic endothelial cells
(Elsevier B.V., 2003-08-15)
The free radical nitric oxide is a very effective signal transducer, stimulating the enzyme guanylyl cyclase, the oncoprotein p21Ras, and protein tyrosine phosphorylation. in the present study using rabbit aortic endothelial ...
