Evidence that a cell-type-specific efflux pump regulates cell differentiation in Dictyostelium.

abstract：:Expression of constitutively active Src protein tyrosine kinase in Xenopus oocytes has been shown to accelerate oocyte maturation suggesting that Src may be involved in meiotic progression. However, meiotic regulation of endogenous Src kinase in oocytes has not been investigated in detail. To address this problem, we ...
