A cDNA for a new ubiquitin-specific protease (UBP), AtUBP5, was identified from Arabidopsis thaliana flower mRNA using an oligonucleotide made against the conserved UBP cysteine (Cys) box. The 924-amino-acid AtUBP5 contains the regions characteristic of all UBPs and has 35% identity and 53% similarity overall to a mammalian UBP (Unp), resulting from additional significant similarity outside these regions. AtUBP5 has 48% identity and 58% similarity overall to two uncharacterized Arabidopsis… CONTINUE READING
