Although overlooked for many years, alternative cleavage and polyadenylation (APA) is now emerging as a major mechanism of gene regulation. A recent study identifies poly(A)-binding protein nuclear 1 (PABPN1), a general factor of polyadenylation, as a suppressor of alternative poly(A) sites.
虽然多年来一直被忽视,但选择性剪接和多聚腺苷酸化 (APA) 现在正成为一种主要的基因调控机制。最近的一项研究确定了多聚腺苷酸结合蛋白核 1 (PABPN1),一种多聚腺苷酸化的通用因子,作为选择性多聚腺苷酸化位点的抑制剂。
