It is a protein-interaction module involved in many important signalling pathways like RNA processing, regulation of histone H3 methylation, innate immunity or embryonic development [1,2,3,4]. It can be divided into 11 subfamilies based on amino acid sequence similarity or the presence of additional protein domains. The greater SPRY family is divided into the SPRY/B30.2 (which contains a PRY extension at the N-terminal) and SPRY-only sub-families which are preceded by a subdomain that is structurally similar to the PRY region [2]. SPRY/B30.2 structures revealed a bent beta-sandwich fold comprised of two beta-sheets. Distant homologues are domains in butyrophilin/ marenostrin/pyrin [1].
