NCBI Protein Information
translocon at the outer envelope membrane of chloroplasts 159
NCBI Summary
An integral membrane GTPase that functions as a transit-sequence receptor required for the import of proteins necessary for chloroplast biogenesis. Located in the outer chloroplast membrane. Phosphorylation of the G-domains regulate translocon assembly.

UniProt Comments
GTPase involved in protein precursor import into chloroplasts. Seems to recognize chloroplast-destined precursor proteins and regulate their presentation to the translocation channel through GTP hydrolysis. Required for chloroplast biogenesis. Probably specialized in the import of nuclear encoded photosynthetic preproteins from the cytoplasm to the chloroplast.
