Tissue-Specific Regulation of Plastid Protein Import via Transit-Peptide Motifs.

Abstract excerpt

Plastids differentiate into various functional types (chloroplasts, leucoplasts, chromoplasts, etc.) that have distinct proteomes depending on the specific tissue. Most plastid proteins are encoded by the nuclear genome, synthesized as higher molecular mass preproteins with an N-terminal transit peptide, and then posttranslationally imported from the cytosol. Evidence for tissue-specific regulation of import into...
