Background Information

CPSF3 (cleavage and polyadenylation specificity factor 3) is involved in human disease and is the putative target of benzoxaboroles in trypanosomatid parasites and Cryptosporidium infection. CPSF3 has also been associated with cancer malignancy in that CPSF3 induces cell cycle arrest in hepatocellular carcinoma and promotes lung adenocarcinoma cell proliferation and metastasis (PMID: 38718887). CPSF3 has been implicated in various cancers, including lung cancer, colorectal, prostate, and triple-negative breast cancers (PMID: 37627085).
