NCBI Protein Information
root cap 1 (RCP1)
NCBI Summary
Encodes a maltose transporter that is expressed in leaves and roots. Mutations at the MEX1 locus cause accumulation of both starch and maltose in leaves, with maltose levels at least 40 times higher than that of wild-type. This gene encodes a protein located in the chloroplast envelope.

UniProt Comments
Probable maltose transporter. Essential for the conversion of starch to sucrose in leaves at night, probably via the export of maltose from the chloroplast. Required for root cap cells formation.
