NCBI Protein Information
translocon at the inner envelope membrane of chloroplasts 20
NCBI Summary
Tic20 is believed to function as a component of the protein-conducting channel at the inner envelope membrane. Genes AT1G04940 and AT1G04945 were switched for the TAIR7 genome release to give consistency with MIPs annotation. The Arabidopsis genome encodes four Tic20 homologous proteins, AT1G04940(Tic20-I), AT2G47840(Tic20-II), AT4G03320(Tic20-IV) and AT5G55710(Tic20-V).

UniProt Comments
Involved in protein precursor import into chloroplasts. May be part of an intermediate translocation complex acting as a protein-conducting channel at the inner envelope. Seems to be specific for photosynthesis-related pre-proteins. Partially redundant with TIC20-IV, but not with TIC20-II or TIC20-V.
