富含絲氨酸和精氨酸的SR蛋白(serine/arginine-richnprotein)是重要的剪接因子家族,廣泛參與RNA加工過程,包括剪接、出核、穩定性及翻譯。nnhttp://cjbmb.bjmu.edu.cn/CN/10.13865/j.cnki.cjbmb.2017.06.01

FunctionEdit SR proteins have been shown to have roles in alternative and constitutive splicing resulting in differential gene expression and also play a part in mRNA export, genome stabilization, non-sense mediated decay, and translation.
