9.B.438.  The Trans Membrane Protein TMEM218 (TMEM218) Family

Most members of the TMEM218 (TM218) Family are small proteins of about 100 - 150 aas with 3 TMSs in a 2 +  1 TMS arrangement. Some are larger with or without more TMSs. They may be involved in ciliary biogenesis or function in eukaryotes. They are primarily found in metazoa, but some are found in Chlorophyta (Viridiplantae).
