ZNF438, also known as Zinc Finger Protein 438, is a member of the zinc finger protein family, distinguished by zinc finger domains that facilitate DNA binding and protein interactions. These proteins play crucial roles in regulating gene expression, chromatin remodelling, and RNA processing. ZNF438 primarily acts as a transcription factor, binding to specific DNA sequences to regulate the activity of target genes, often collaborating with other transcriptional regulators and chromatin modifiers to precisely control cellular processes.
