description | Protein which contains at least one sushi domain, a motif of approximately 60 amino acids characterized by a framework of four conserved half-cystine residues (1-3 and 2-4 disulfide-bonded) and several other highly conserved residues including proline, tryptophan, tyrosine/phenylalanine and cysteine. This type of structure, also designated SCR (Short Consensus Repeat), is predominantly present in proteins associated with the complement system |
