Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily: XS domain

Structural domains comprising this superfamily share the structure of the XS domain (named after rice gene X and SGS3), a single-stranded RNA-binding domain (RBD) which shows a unique RNA recognition motif (RRM) fold PMID:18635957. Its function remains unknown but the plant SGS3 proteins are thought to be involved in post-transcriptional gene silencing (PTGS) pathways PMID:22592791.
