BURP domain The BURP domain is found at the C-terminus of several different plant proteins. It was named after the proteins in which it was first identified: the BNM2 clone-derived protein from Brassica napus; USPs and USP-like proteins; RD22 from Arabidopsis thaliana; and PG1beta from Lycopersicon esculentum. This domain is around 230 amino acid residues long. It possesses the following conserved features: two phenylalanine residues at its N-terminus; two cysteine residues; and four repeated cysteine-histidine motifs, arranged as: CH-X(10)-CH-X(25-27)-CH-X(25-26)-CH, where X can be any amino acid. The function of this domain is unknown. |
