Activity summary

The protein SMYD4 also known as SET and MYND domain-containing protein 4 functions mechanically as a histone methyltransferase responsible for trimethylating histone H4 at lysine 20. This modification plays a role in chromatin structure and gene expression regulation. SMYD4 has a molecular mass of approximately 92 kDa. This protein is expressed in several tissues with higher expression observed in the central nervous system and skeletal muscle tissues.

Biological function summary

SMYD4 participates in the regulation of gene expression and cellular development. It functions by joining protein complexes that modify chromatin influencing gene transcription. Through its histone methyltransferase activity SMYD4 changes the chromatin state which is essential for fine-tuning developmental gene expression patterns. These modifications are integral for proper cell differentiation and vertebrate organogenesis.

Pathways

The activity of SMYD4 intersects notably with pathways regulating epigenetic modification and cell differentiation. SMYD4 interacts with the Wnt signaling pathway an important route for cell fate determination and organ patterning. It also relates to histone-modifying complexes like those involving the protein EZH2 which contributes to the polycomb repressive complex 2 (PRC2) facilitating transcriptional repression.

Associated diseases and disorders

The dysregulation of SMYD4 activity links to certain cancers and neurodevelopmental disorders. Specifically it shows connection to breast cancer where aberrant expression levels can influence tumor progression by altering the transcription of oncogenes and tumor suppressor genes. Additionally SMYD4 interacts with proteins such as BRCA1 in breast cancer pathways affecting DNA repair mechanisms and genomic stability. Moreover studies suggest that changes in SMYD4 expression levels may have implications in developmental disorders affecting brain functionality.
