Abstract:Dysregulation of human DNA polymerase delta (Polδ) subunits is associated with genome instability and pathological disorders. Genome databases suggest the expression of several spliced variants of subunits which may alter Polδ function. Here, we analyzed the protein‐encoding variants of the Polδ subunit p12 and their association with cancer. p12 isoform‐2 (p12*) encodes a 79 aa protein with a C‐terminal tail distinct from the previously characterized p12. Like p12, p12* dimerizes and interacts with p125 and p5… Show more
