This entry represents a WH-like domain present in SSO1393-like proteins. SSO1393 is an archaeal protein from Sulfolobus solfataricus (PDB:3qyf). This protein has been described as a component of the CRISPR system [1]. CRISPR (clustered regularly interspaced short palindromic repeat) is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements and conjugative plasmids) [1,2].
