TSC22 Domain Family, Member 1, DKFZp686O19206, RP11-269C23.2

TSC22 domain family protein, or TSC22, is a transcription factor that belongs to the large family of early response genes. This transcriptional repressor is known to act on the C-type natriuretic peptide (CNP) promoter. TSC22 belongs to the TSC-22:Dip:Bun family and is an intracellular protein that may be found in the cytoplasm or nucleus. This transcription factor is known to regulate cell growth, differentiation and cell death and is involved in modulating the transcriptional activity of Smad3 and Smad4. This protein is ubiquitously expressed in most tissues and widely in both fetal and adult tissues. It is generally expressed in aortic endothelial cells, and induced by cytokines, including TGFB. These proteins may be possible therapeutic targets of leukemia and prostate cancer.
