Linker domain Ser-phosphorylation as a putative modulator for ABCB alkaloid transporters
Structural similarities within the linker domain of different ABCB-type proteins revealed structural similarities within the linker domain, including the presence of [R/K-X-S/T] and [R/K-X-X-S/T] motifs, which are potential phosphorylation sites for kinases of the AGCVIII superfamily, and a phosphorylation-based regulatory mechanism is proposed for ABCB alkaloid transporters.
