The process of directing proteins towards the chloroplast, usually using signals contained within the protein. Imported proteins are synthesized as cytosolic precursors containing N-terminal uptake-targeting sequences that direct each protein to its correct subcompartment and are subsequently cleaved. The process of directing proteins towards a membrane, usually using signals contained within the protein. The import of proteins into the chloroplast thylakoid membranes. Proteins that are destined for the thylakoid lumen require two uptake-targeting sequences: the first targets the protein to the stroma, and the second targets the protein from the stroma to the thylakoid lumen. Four separate thylakoid-import systems deal with the proteins once they are in the stroma. The directed movement of proteins into a cell or organelle. The process of targeting specific proteins to particular membrane-bounded subcellular organelles. Usually requires an organelle specific protein sequence motif. The directed movement of proteins into, out of, within or between cells by means of some external agent such as a transporter or pore.
