From: Molecular and functional analyses of COPT/Ctr-type copper transporter-like gene family in rice
Analyses of the interactions of rice COPTs protein by split-ubiquitin system. The growth of yeast cells on selective medium and the expression of reporter protein a-galactosidase (X-a-gal) indicate the homomeric or heteromeric interactions of COPTs. AIg5, a transmembrane protein with C terminal in the cytoplasm; NubI, N-terminal half of ubiquitin protein; NubG, mutated N-terminal half of ubiquitin protein; Cub, C-terminal half of ubiquitin protein; Leu, leucine; Trp, tryptophan; His, histidine; Ade, adenine.
