Objective To construct the stable HeLa cell lines with SOSSB1,SOSSB2 and SOSSC genes knocked out.Methods The A and B sgRNAs(single guide RNA)targeting to exons of SOSSB1,SOSSB2 and SOSSC genes and the complementary strands were designed and synthesized,then inserted into Bbs Ⅰ cohesive ends-containing PX462 linear vector. The constructed recombinant plasmids were identified by restriction analysis and sequencing and transfected to HeLa cells. The stable HeLa cells were screened with 2 μg/mL puromycin. The r...
SOSS复合物是单链DNA结合蛋白(single-stran-ded DNA binding proteins,SSBs)复合物,由SOSS1和SOSS2构成。SOSS1主要由INTS3(SOSSA)、hSSB1(SOSSB1)和C9orf80(SOSSC)组成[1],SOSS2与其组成相似,主要区别为SOSS2复合物用hSSB2(SO-SSB2)代替hSSB1(SOSSB1)。SOSS1和SOSS2在功能上?
