背景信息

The CstF-64 antibody is a crucial tool in studying the Cleavage Stimulation Factor (CstF) complex, a key component in eukaryotic mRNA 3′-end processing. CstF-64. a 64 kDa subunit of the CstF complex, binds GU-rich elements downstream of polyadenylation signals, facilitating RNA polymerase II termination and pre-mRNA cleavage. It contains an N-terminal RNA recognition motif (RRM) and a C-terminal domain that interacts with CstF-77. another core subunit. Research has highlighted its role in alternative polyadenylation (APA), which regulates mRNA diversity and gene expression. Notably, CstF-64 exhibits tissue-specific isoforms, including a testis-specific variant (tauCstF-64) critical for male germ cell development. Dysregulation of CstF-64 is linked to diseases like cancer, where altered APA promotes oncogene expression. The antibody enables detection, localization, and functional analysis of CstF-64 in various models, aiding investigations into mRNA processing mechanisms, reproductive biology, and disease pathogenesis. Commercial antibodies are typically raised against conserved epitopes, validated through techniques like Western blotting and immunofluorescence. Its applications span basic research, biomarker studies, and therapeutic target exploration.
