Abstract

We report a cDNA encoding a 71-kDa protein with a single high-mobility group (HMG) box and two nuclear localization signals from the higher plant Catharanthus roseus (Madagascar periwinkle). The protein had 40% amino acid identity with animal DNA-binding proteins of the SSRP (structure-specific recognition protein) family that recognize bent, unwound DNA structures. Genomic Southern analysis suggested the presence of two genes.

摘要

我们报道了一种来自高等植物长春花（马达加斯加长春花）的cDNA，它编码一种71 kDa的蛋白质，该蛋白质具有一个单一的高迁移率族（HMG）框和两个核定位信号。该蛋白质与识别弯曲、解旋DNA结构的SSRP（结构特异性识别蛋白）家族的动物DNA结合蛋白具有40%的氨基酸同一性。基因组Southern分析表明存在两个基因。
