| Type: | Domain | Name: | XS domain |
| Description: | The XS (rice gene X and SGS3) domain is found in a family of plant proteins including gene X and SGS3 . SGS3 is involved in post-transcriptional gene silencing (PTGS) and natural virus resistance []. This domain contains a conserved aspartate residue that may be functionally important.The XS domain containing proteins contain coiled-coils, which suggests that they will oligomerise. Most coiled-coil proteins form either a dimeric or a trimeric structure. It is possible that different members of the XS domain family could oligomerise via their coiled-coils forming a variety of complexes []. This entry also includes Protein INVOLVED IN DE NOVO 2 []. | Short Name: | XS_domain |
