Welcome to BURP !

The BURP domain-containing proteins were characterized by the conserved C-terminal domain, which was named based on four typical members: BNM2, USP, RD22 and PG1β. Generally, BURP domain-containing proteins contained several conserved modules: a putative signal peptide at the N-terminal hydrophobic domain; the BURP domain at the C-terminus, which included several conserved amino acid sites and four repeat cysteine-histidine (CH) motifs; the variable region in the middle, unique to each BURP protein, which included a short-conserved segment or other short segments; and an optional segment consisting of repeated units. BURP domain-containing proteins have been found only in plants, indicating that these proteins played significant roles in the development of reproductive organs, such as anther, microspore and seed, and in the metabolism of pectin in the cell wall.
