    Background

    Regulation of nuclear pre-mRNA domain-containing 1B (RPRD1B), also known as cell cycle-related and expression-elevated protein in tumor (CREPT), is a transcriptional regulator that interacts with the POLR2A catalytic subunit of RNA polymerase II (Pol II) (1). It is also an oncoprotein that promotes cell proliferation and is upregulated in a variety of cancers, including gastric, colorectal, and non-small cell lung cancer (NSCLC) (2-4). RPRD1B contains a CTD-interacting domain (CID), which interacts with the C-terminal domain (CTD) of Pol II to regulate transcription termination (5). It is believed that this association enhances the binding of Pol II to the CCND1 promoter, thereby increasing cyclin D1 transcription and promoting tumorigenesis (6). Specifically, RPRD1B promotes chromatin looping of the CCND1 gene to recycle Pol II from the termination site to the promoter region (6). RPRD1B may also regulate the transcription of various genes through associations with STAT3 and the histone acetyltransferase p300 (7,8).
