CC -!- FUNCTION: Required during embryogenesis. Permease involved in lipid
CC transfer from the endoplasmic reticulum (ER) to plastids, and necessary
CC for thylakoids formation. {ECO:0000269|PubMed:12743031,
CC ECO:0000269|PubMed:16199613, ECO:0000269|PubMed:18689504,
CC ECO:0000269|PubMed:20410050}.
CC -!- SUBUNIT: Permease subunit of the TGD complex, a lipid translocator at
CC the inner chloroplast envelope membrane made of TGD1, TGD2 and TGD3
CC (PubMed:22544736). Interacts with TGD2 and TGD3 with an overall subunit
CC stoichiometry of 2 TGD1, 2 TGD3 and 8 to 12 TGD2 (PubMed:22544736).
CC Interacts with TGD5 (PubMed:26410300). {ECO:0000269|PubMed:22544736,
CC ECO:0000269|PubMed:26410300}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast inner membrane
CC {ECO:0000269|PubMed:12743031, ECO:0000269|PubMed:16199613}; Multi-pass
CC membrane protein {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: High levels in green tissues, but low levels in
CC nongreen tissues such as roots. {ECO:0000269|PubMed:12743031}.
CC -!- DISRUPTION PHENOTYPE: Disruption in the biosynthesis of ER-derived
CC thylakoid lipids, and accumulation of oligogalactolipids,
CC triacylglycerols (TAGs), and phosphatidates (PAs). Reduced growth with
CC stout leaves and siliques. Impaired embryogenesis.
CC {ECO:0000269|PubMed:12743031, ECO:0000269|PubMed:16199613}.
CC -!- SIMILARITY: Belongs to the MlaE permease family. {ECO:0000305}.
CC -!- CAUTION: Was originally (PubMed:18299247) thought to belong to the ABC
CC transporter family. Lacks the conserved ABC domain, which is one of the
CC features of the ABC transporter family. {ECO:0000305|PubMed:18299247}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAG12551.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
