Protein Family Models

This domain is found repeated three times in the N-terminal half of the gliding motility-related SprA proteins. The role of this domain in motility is uncertain [1]. It is also found in proteins required for secretion [2]. [1]. 17644580. Flavobacterium johnsoniae SprA is a cell surface protein involved in gliding motility.
