SPRY
PFAM accession number:PF00622
Interpro abstract (IPR003877): The SPRY domain is named from SPla and the RYanodine Receptor. Its function is unknown. Distant homologues are domains in butyrophilin/marenostrin/pyrin [(PUBMED:9204703)]. Ca2+-release from the sarcoplasmic or endoplasmic reticulum, the intracellular Ca2+ store, is mediated by the ryanodine receptor (RyR) and/or the inositol trisphosphate receptor (IP3R).
GO function:protein binding (GO:0005515)
