NCBI Protein Information
ATP-binding cassette I15
NCBI Summary
Encodes a permease-like component of an ABC transporter involved in lipid transfer from ER to chloroplast. A phosphatidic acid-binding protein with a predicted mycobacterial cell entry domain. It is tethered to the inner chloroplast envelope membrane facing the outer envelope membrane. Presumed bacterial orthologs of TGD1 and TGD2 in Gram-negative bacteria are typically organized in transcriptional units, suggesting their involvement in a common biological process. Mutations in this gene suppress the low temperature-induced phenotype of Arabidopsis tocopherol-deficient mutant vte2.

UniProt Comments
Component of a phosphatidic acid/lipid transport complex in the chloroplast envelope. Specifically binds phosphatidic acid (PA). Involved in lipid transfer from the endoplasmic reticulum (ER) to plastids, and necessary for thylakoids formation.
