Abstract

hPFTAIRE1 is a member of Cdc2-related kinase family localized in cytoplasm. To search its substrates and regulatory proteins, the hPFTAIRE1 was fused to LexA and used as bait to screen a human brain LexA two-hybrid library. In this screening, 7 hPFTAIRE1 interacting proteins, including KIAA0202, were obtained. The interaction between the KIAA0202 and the hPFTAIRE1 was confirmed by using immunoprecipitation. The KIAA0202 is a 508 aa protein and is a member of septin family. The central portion of the KIAA0202 is a GTP-CDC domain, which is conserved among almost all septins. Its C-terminus is a coiled-coil structure and its N-terminus is a variable region. Our results suggest that the KIAA0202 may play important roles in functional regulation of hPFTAIRE1.

摘要

hPFTAIRE1是一种定位于细胞质的Cdc2相关激酶家族成员。为了寻找其底物和调节蛋白，将hPFTAIRE1与LexA融合，并用作诱饵来筛选人脑LexA双杂交文库。在这次筛选中，获得了7种与hPFTAIRE1相互作用的蛋白，包括KIAA0202。通过免疫沉淀证实了KIAA0202与hPFTAIRE1之间的相互作用。KIAA0202是一种含508个氨基酸的蛋白，是septin家族的成员。KIAA0202的中央部分是一个GTP-CDC结构域，几乎在所有septin中都保守。其C末端是一个卷曲螺旋结构，N末端是一个可变区域。我们的结果表明，KIAA0202可能在hPFTAIRE1的功能调节中发挥重要作用。
