TFCP2 (Transcription Factor CP2): TFCP2,also known as LSF (Late SV40 Factor), is a transcription factor that regulates gene expression by binding to GC-rich promoter regions of target genes. It plays important roles in various biological processes such as cell cycle progression, liver regeneration, and viral replication. TFCP2’s involvement in cell proliferation and differentiation links it to development and diseases like cancer, where transcription factor dysregulation can lead to abnormal cell growth and tumor progression.
