ZGRF1, also known as Zinc finger GRF-type containing 1, is a protein defined by the presence of zinc finger domains — common motifs involved in binding nucleic acids and mediating protein-protein interactions. Located primarily in the cell nucleus, ZGRF1 is believed to function as a transcription factor or regulator of gene expression. Although the precise roles of ZGRF1 are still being studied, zinc finger proteins generally play key roles in various cellular processes such as gene transcription, RNA processing, and chromatin remodeling. These proteins can act as transcriptional activators or repressors by binding to specific DNA sequences.
