ETS2 (ETS Proto-Oncogene 2, Transcription Factor): ETS2 is a gene that encodes a transcription factor from the ETS family. Transcription factors like ETS2 regulate the expression of specific target genes by binding to particular DNA sequences. ETS2 plays important roles in cellular processes such as cell proliferation, differentiation, and development. Dysregulation of ETS2 has been linked to cancer and developmental disorders.
