NCBI Protein Information
translocon at the outer envelope membrane of chloroplasts 75-III
NCBI Summary
Component of the translocon outer membrane (TOC) complex. Forms the outer envelope translocation channel (beta-barrel). Plays a role in preprotein conductance. Imported into chloroplast. Expressed in young dividing photosynthetic tissues. Knockout mutants are embryo lethal with arrested development at the two-cell stage. Knockout mutants have abnormal etioplasts.

UniProt Comments
Essential protein. Mediates the insertion of proteins targeted to the outer membrane of chloroplasts . Required for the import of protein precursors into chloroplasts. Forms the voltage-dependent preprotein translocation channels (hydrophilic beta barrel) of the TOC complex in the chloroplastic outer membrane.
