MORN repeat Add an annotation

The MORN (Membrane Occupation and Recognition Nexus) repeat is found in multiple copies in several proteins including junctophilins (See Takeshima et al. Mol. Cell 2000;6:11-22). A MORN-repeat protein has been identified in the parasite Toxoplasma gondiis as dynamic component of cell division apparatus [1]. It has been hypothesised to function as a linker protein between certain membrane regions and the parasite's cytoskeleton [1].

This clan contains 2 families and the total number of domains in the clan is 71359. The clan was built by J Mistry.

Interacting families


For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the MSD group, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between the Pfam families in this clan, the corresponding UniProt entries, and the region of the three-dimensional structures that are available for that sequence.
