Chloroplast envelope protein translocase (CEPT); outer membrane complex. The Tic20-like protein (acc # AUO68237.1; 413 aas, 6 TMSs in a 1 TMS (N-terminal) + 5 TMSs (C-terminal)), of the lower brown alga, Saccharina japonica, has been characterized (Chen et al. 2019).

The chloroplast envelope TIC translocase (TIC) complex. Tic21, Tic20-I, Tic214, Tic100 and Tic56 plus Toc components comprise a 1 Md complex in the membrane with each component being present in stoichiometric amounts (Teng et al. 2006; Kikuchi et al. 2013).  A 1-megadalton complex consisting of Tic21, Tic20, Tic56, Tic100, and Tic214 has been identified in the chloroplast inner membrane (Nakai 2015).
