B30.2/SPRY domain superfamily
IPR043136
Definition
This superfamily also matches diverse E3 ubiquitin-protein ligases. This protein is involved in the apoptosis process [[cite:PMID:19100260], [cite:PMID:22529100]]. The B30.2 domain was first identified as a protein domain encoded by an exon (named B30-2) in the Homo sapiens class I major histocompatibility complex region PMID:8114113, whereas the SPRY domain was first identified in a Dictyostelium discoideum kinase splA and mammalian calcium-release channels ryanodine receptors PMID:9204703. B30.2 domain consists of PRY and SPRY subdomains. The SPRY domains (after SPla and the RYanodine Receptor) are shorter at the N terminus than the B30.2 domains. The ~200-residue B30.2/SPRY (for B30.2 and/or SPRY) domain is present in a large number of proteins with diverse individual functions in different biological processes. The B30.2/SPRY domain in these proteins is likely to function through protein-protein interaction PMID:16498413. The N-terminal ~60 residues of B30.2/SPRY domains are poorly conserved and, as a consequence, a new domain name PRY was coined for a group of similar sequence segments N-terminal to the SPRY domains PMID:16498413. The B30.2/SPRY domain contains three highly conserved motifs (LDP, WEVE and LDYE) PMID:9196055. The B30.2/SPRY domain adopts a highly distorted, compact β-sandwich fold with two additional short β-helices at the N terminus. The β-sandwich of the B30.2/SPRY domain consists of two layers of β-sheets: sheet A composed of eight strands and sheet B composed of seven strands. All the β-strands are in antiparallel arrangement PMID:16498413. The 5th β-strand corresponding to WEVE motif PMID:10223295. Both the N- and C-terminal ends of the B30.2/SPRY domains in general are close to each other PMID:16498413.
