Activated RNA polymerase II transcriptional coactivator p15 also known as positive cofactor 4 (PC4) or SUB1 homolog is a protein that in humans is encoded by the SUB1 gene.^[1][2][3] The human SUB1 gene^[3] is named after an orthologous gene in yeast.^[4]

Interactions

SUB1 has been shown to interact with CSTF2.^[5]
