P. Lucero et al., Monoubiquitination is sufficient to signal internalization of the maltose transporter in Saccharomyces cerevisiae, J BACT, 182(1), 2000, pp. 241-243
Monoubiquitination of the 12-transmembrane segment (12-TMS) Saccharomyces c
erevisiae maltose transporter promoted the maximal internalization rate of
this protein. This modification is similar to that of the 7-TMS alpha-facto
r receptor but different from that of the 12-TMS uracil and general amino a
cid permeases. This result shows that binding of ubiquitin-Lys63 chains is
not required for maximal internalization of all 12-TMS-containing proteins.
