    We have isolated a new gene (PTK2) which restores spermine uptake of a polyamine uptake-deficient mutant of Saccharomyces cerevisiae (Kakinuma, Y., Maruyama, T., Nozaki, T., Wada, Y., Oshumi, Y., and Igarashi, K., 1995, Biochem, Biophys...

    ..We show here that deletion of SKY1 or PTK2 in trk1,2Delta cells increase spermine tolerance, implying Trk1,2p independent activity...

    ..While deletion or overexpression of SKY1 did not significantly affect Pma1p activity, the ability of overexpressed Sky1p, Ptk1p, and Ptk2p to increase sensitivity to LiCl depends on the integrity of PPZ1 but not of ENA1. ..
