基因研究概述
SRSF7(Serine/arginine-rich splicing factor 7),也称为富含丝氨酸/精氨酸的剪接因子7,是一种重要的RNA结合蛋白,属于SR蛋白家族。SR蛋白家族是一类广泛存在于真核生物中的RNA结合蛋白,在mRNA前体(pre-mRNA)的剪接过程中发挥重要作用。SRSF7参与调节mRNA前体的剪接,影响mRNA的稳定性和功能,进而影响基因表达和生物学过程。
SRSF7在多种生物学过程中发挥作用,包括细胞增殖、迁移、免疫反应、肿瘤进展和病毒感染。例如,研究发现SRSF7通过调节m6A修饰,促进胶质母细胞瘤(GBM)的进展[1]。此外,SRSF7还参与调节I型干扰素反应,通过激活IRF7转录促进抗病毒免疫[2]。SRSF7还与Microprocessor复合物相互作用,影响miRNA的生物合成[3]。此外,SRSF7还参与调节小鼠卵母细胞发育过程中的选择性多腺苷酸化和选择性剪接[4]。此外,SRSF7还参与调节核斑点的形成,与SRRM2共同构成核斑点的核心结构[5]。SRSF7在肝细胞癌(HCC)中表达上调,与不良预后相关,可能成为预测HCC预后的生物标志物[6]。此外,SRSF7还通过表达Split-ORFs和核体组装维持其自身蛋白稳态[7]。SRSF7还参与调节流感病毒A的聚合酶活性和复制[8]。此外,SRSF7还通过调节p21水平影响结肠癌细胞的生长[9]。此外,SRSF7还参与调节骨肉瘤的预后和免疫调节状态[10]。
综上所述,SRSF7是一种重要的RNA结合蛋白,在多种生物学过程中发挥作用,包括细胞增殖、迁移、免疫反应、肿瘤进展和病毒感染。SRSF7的研究有助于深入理解RNA结合蛋白的生物学功能和疾病发生机制,为疾病的治疗和预防提供新的思路和策略。
