T cell development requires phosphatidylinositol 3-kinase (PI3K) signaling with contributions from both the class IA, p110delta, and class IB, p110gamma catalytic subunits. However, the receptors on immature T cells by which each of these PI3Ks are activated have not been identified, nor has the mechanism behind their functional redundancy in the thymus.(More)
BACKGROUND Protein tyrosine phosphorylation is one of the main processes associated with sperm activation. Although this process and its targets have been well characterized, only few tyrosine kinases have been identified so far and their roles in spermatozoa are still largely unknown. In this study, we report the presence and localization of Src kinase in(More)
