Biochem/physiol Actions

SETD8 expression is observed in cancers such as bladder cancer, chronic myelogenous leukemia, hepatocellular carcinoma, non‐small‐cell lung carcinoma, prostate cancer, small‐cell lung carcinoma. Therefore inhibition of SETD8 (SET‐domain containing protein) by UNC0379 might prevent the progression of cancer.
UNC0379 is the first substrate-competitive inhibitor of the lysine methyltransferase SETD8, the only known methyltransferase that catalyzes monomethylation of histone H4 lysine 20 (H4K20). HK420 methylation has been implicated in the regulation of a variety of biological processes including the DNA damage response. UNC0379 is selective for SETD8 over 15 other methyltransferases, with an IC50 value of 7.3 μM for SETD8 compared to IC50 vlaues over 100 μM for other methyltransferases.

Cip1-interacting zinc finger protein 1 (CIZ1) forms RNA-dependent protein assemblies that stabilise epigenetic state, notable at the inactive X chromosome in females. CIZ1 has been linked with a range of human cancers and in mice genetic deletion of CIZ1 manifests

The histone methyltransferase SETD8, which methylates the lysine 20 of histone H4 (H4K20), is reportedly involved in human carcinogenesis along with nonhistone proteins such as p53. However, its expression profiles and functions in the context of high-grade serous ovarian carcinoma
