Activation of protein tyrosine kinase: A possible requirement for fixed-bacteria and lipopolysaccharide-induced increase in human natural killer cell activity
(1996)
Preincubation of peripheral blood lymphocytes (PBL) from drug-free, healthy volunteers with either the protein tyrosine kinase inhibitor genistein (GNT, n = 10, final concentration 200 μM) or the protein kinase A activator ...
Activation of spleen tyrosine kinase (Syk) at fertilization in Rhinella arenarum eggs
(U B C Press, 2014-12)
Recently, we have provided evidence for the involvement of a cytosolic tyrosine–phosphorylatable 70 kDa oocyte protein in Rhinella arenarum (Anura: Bufonidae) fertilization. The aim of the present work was to characterize ...
The tyrosine kinase FER is responsible for the capacitation-associated increase in tyrosine phosphorylation in murine sperm
(Company of Biologists, 2016-07)
Sperm capacitation is required for fertilization. At the molecular level, this process is associated with fast activation of protein kinase A. Downstream of this event, capacitating conditions lead to an increase in tyrosine ...
