Zfp523, a member of the zinc finger family of transcription factors, is involved in gene regulation. It was found to interact with TATA-binding protein (TBP), suggesting its potential role in the regulation of transcription initiation, an essential biological process for gene expression [1].

In the study of vascular dementia (VaD), Zfp523 was identified as one of the significant transcription factors in the miRNA-TF-target gene network. The network analysis showed that genes associated with Zfp523 were mainly involved in pathways like PI3K/Akt, neuroactive ligand-receptor interaction, calcium signaling, and Wnt signaling pathways. These pathways are crucial for normal neuronal function, and their dysregulation may contribute to the development of VaD [2].

In conclusion, Zfp523 plays a role in transcription-related processes through its interaction with TBP and is associated with pathways relevant to vascular dementia. Understanding Zfp523's functions in these contexts may provide insights into the molecular mechanisms of normal gene regulation and the pathogenesis of VaD.
