Pancreatic differentiation 2 (PD2)/RNA polymerase II-associated factor 1 (PAF1)
is the core subunit of the human PAF1 complex (PAF1C) that regulates the
promoter-proximal pausing of RNA polymerase II as well as transcription
elongation and mRNA processing and coordinates events in mRNA stability and
quality control. As an integral part of its transcription-regulatory function,
PD2/PAF1 plays a role in posttranslational histone covalent modifications as well
as regulates expression of critical genes of the cell-cycle machinery. PD2/PAF1
alone, and as a part of PAF1C, provides distinct roles in the maintenance of
self-renewal of embryonic stem cells and cancer stem cells, and in lineage
differentiation. Thus, PD2/PAF1 malfunction or its altered abundance is likely to
affect normal cellular functions, leading to disease states. Indeed, PD2/PAF1 is
found to be upregulated in poorly differentiated pancreatic cancer cells and has
the capacity for neoplastic transformation when ectopically expressed in mouse
fibroblast cells. Likewise, PD2/PAF1 is upregulated in pancreatic and ovarian
cancer stem cells. Here, we concisely describe multifaceted roles of PD2/PAF1
associated with oncogenic transformation and implicate PD2/PAF1 as an attractive
target for therapeutic development to combat malignancy. Cancer Res; 78(2);
