Alternative polyadenylation (APA) occurs in the process of mRNA maturation by adding a poly(A) tail Disposable Cutlery at different locations, resulting increased diversity of mRNA isoforms and contributing to the complexity of gene regulatory network.Benefit from the development of high-throughput sequencing technologies, we could now delineate APA profiles of transcriptomes at an unprecedented pace.Especially the single cell RNA sequencing (scRNA-seq) technologies provide us opportunities to interrogate biological details of diverse and rare cell types.Despite increasing evidence showing that APA is involved in the cell type-specific regulation and function, efficient and specific laboratory methods for capturing poly(A) sites at single cell resolution are underdeveloped to date.

In this review, we summarize existing experimental and computational methods for the door stop identification of APA dynamics from diverse single cell types.A future perspective is also provided.
