The Cleavage and Polyadenylation Specificity Factor subunit 6 (CPSF6) is a key component of the mammalian mRNA 3′-end processing machinery, which ensures proper cleavage and polyadenylation of pre-mRNAs during transcription termination. As part of the CPSF complex, CPSF6 recognizes specific RNA sequence elements (e.g., UGUA motifs) and facilitates interactions with other processing factors to coordinate mRNA maturation. It plays a critical role in regulating alternative polyadenylation, a mechanism that influences mRNA stability, localization, and protein diversity. Recombinant human CPSF6 protein is engineered for in vitro studies to dissect its molecular functions, structural properties, and interactions with viral or cellular partners. Research highlights its involvement in viral replication, particularly HIV-1. where CPSF6's binding to the viral capsid affects nuclear entry and integration. Dysregulation of CPSF6 has also been linked to cancers and developmental disorders, underscoring its physiological importance. Recombinant CPSF6. typically expressed in Escherichia coli or mammalian systems with purification tags, enables biochemical assays, structural analyses (e.g., crystallography), and high-throughput screening for therapeutic agents targeting mRNA processing pathways. Its study provides insights into gene expression regulation and potential treatment strategies for infections and genetic diseases.
