背景信息

Recombinant human CPSF3L (Cleavage and Polyadenylation Specificity Factor 3-like) protein is a key subject in studying post-transcriptional RNA processing. CPSF3L, part of the evolutionarily conserved cleavage and polyadenylation specificity factor (CPSF) complex, plays a critical role in mRNA 3′-end formation. Unlike its paralog CPSF3 (CPSF73), which directly catalyzes pre-mRNA cleavage during polyadenylation, CPSF3L has been implicated in alternative or auxiliary regulatory mechanisms, though its precise function remains under investigation. Some studies suggest involvement in specialized polyadenylation events, transcription termination, or interactions with other RNA-processing factors.

Produced via recombinant DNA technology, CPSF3L is typically expressed in bacterial or mammalian systems and purified for functional studies. Researchers leverage this protein to dissect its enzymatic properties, substrate specificity, and structural features, often comparing it with CPSF3 to clarify functional divergence. Its recombinant form also aids in exploring potential roles in diseases linked to dysregulated RNA processing, such as cancers or neurological disorders, where altered polyadenylation patterns influence gene expression. Additionally, it serves as a tool for developing inhibitors targeting mRNA processing pathways, offering therapeutic potential. Understanding CPSF3L’s biology advances insights into gene expression regulation and RNA maturation, bridging fundamental biochemistry with translational applications.
