Abstract This is a domain found in ryanodine, inositol trisphosphate receptor and protein O-mannosyltransferase. Inositol 1,4,5-trisphosphate (InsP3) is an intracellular second messenger that transduces growth factor and neurotransmitter signals. InsP3 mediates the release of Ca2+ from intracellular stores by binding to specific Ca2+ channel-coupled receptors. Ryanodine receptors are involved in communication between transverse-tubules and the sarcoplamic reticulum of cardiac and skeletal muscle. The proteins function as a Ca2+-release channels following depolarisation of transverse-tubules [PubMed1645727]. The function is modulated by Ca2+, Mg2+, ATP and calmodulin. Deficiency in the ryanodine receptor may be the cause of malignant hyperthermia (MH) and of central core disease of muscle (CCD) [PubMed7829078]. protein O-mannosyltransferases transfer mannose from DOL-P-mannose to ser or thr residues on proteins.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 2 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a MIR domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 2 hidden Markov models representing the MIR domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
