The L6 membrane proteins--a new four-transmembrane superfamily

Protein Sci. 2000 Aug;9(8):1594-600. doi: 10.1110/ps.9.8.1594.

Abstract

L6, IL-TMP, and TM4SF5 are cell surface proteins predicted to have four transmembrane domains. Previous sequence analysis led to their assignment as members of the tetraspanin superfamily. In this paper, we identify a new sequence (L6D) that is strikingly similar to L6, IL-TMP, and TM4SF5. Analyses of these four sequences indicate that they are not significantly related to genuine tetraspanins, but instead constitute their own L6 superfamily.
