Outer membrane OMP85 family protein
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. Knockout mutants have abnormal etioplasts.

UniProt Comments
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 . Required for etioplast formation and/or etioplast-chloroplast transition during deetiolation.
