KMT1E also known as SETDB1 is a lysine methyltransferase with a role in epigenetic regulation. This enzyme has a molecular weight of approximately 143 kDa. It actively methylates histone H3 at lysine 9 (H3K9) a modification associated with transcriptional repression. SETDB1 contains a SET domain responsible for its methyltransferase activity. Expressed mainly in the nucleus this enzyme plays a critical role in controlling gene expression across various tissues including the brain spleen and testis.
Biological function summary
The methyltransferase SETDB1 impacts chromatin structure and gene silencing. It operates as a part of the histone methylation complex collaborating with co-factors like ATF7IP and MBD1 to achieve highly specific gene repression. By catalyzing trimethylation of H3K9 it creates a binding site for HP1 proteins facilitating the formation of heterochromatin. This action is essential for processes such as X-chromosome inactivation and the repression of transposable elements.
Pathways
Regulation through SETDB1 influences key biological processes. This enzyme is integral to the PRC2 (Polycomb Repressive Complex 2) pathway maintaining transcriptional silencing during development. Furthermore SETDB1 works alongside SUV39H1 in dynamic change of heterochromatin states regulating genes involved in cell cycle and differentiation. Such pathways highlight its significant interactions with proteins like EZH2 and EED which assist in maintaining stable gene silencing.
SETDB1 shows a connection with cancer particularly in melanoma and lung cancer. Overexpression or dysregulation of SETDB1 can lead to aberrant methylation patterns contributing to oncogenesis through alteration of tumor suppressor genes. Additionally schizophrenia has an association with SETDB1 where improper histone modification can impact gene expression programs critical for neurological function. In these contexts proteins such as DNMT1 also play a role as they collaborate in epigenetic modifications linked to the disease development.
