2.A.7.4.6
Red1; UMAMIT18; WAT1-related protein At1g44800, or SIART of 370 aas and 10 TMSs. It is an L-amino acid efflux transporter that can function bidirectionally into and out
of the cell (Müller et al. 2015). In Arabidopsis, SIAR1 localizes to the plasma
membrane and is expressed in the vascular tissue, in the pericycle, stamen, and the chalazal seed coat of ovules and developing seeds.
Mutant alleles of SIAR1 accumulate anthocyanins as a symptom of reduced
amino acid content in the early stages of silique development (Ladwig et al. 2012).
