Gene ID: 7040 is TGFB1 transforming growth factor beta 1. "This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate a latency-associated peptide (LAP) and a mature peptide, and is found in either a latent form composed of a mature peptide homodimer, a LAP homodimer, and a latent TGF-beta binding protein, or in an active form consisting solely of the mature peptide homodimer. The mature peptide may also form heterodimers with other TGFB family members. This encoded protein regulates cell proliferation, differentiation and growth, and can modulate expression and activation of other growth factors including interferon gamma and tumor necrosis factor alpha. This gene is frequently upregulated in tumor cells, and mutations in this gene result in Camurati-Engelmann disease."<ref name=RefSeq2016>{{ cite web

"Transforming growth factor beta (TGFβ) is implicated in the regulation of smooth muscle cell (SMC) differentiation. [A] novel TGFβ control element (TCE) [occurs] in the promoters of SMC differentiation marker genes including α SM actin and SM22α."[1]

The "promoters of multiple other SMC differentiation marker genes including SM22α and SM-MHC were also found to contain similar TCE regions [11]."[1]

The "α SM actin CArG element (CArG A) was required in combination with the TCE to coordinately regulate TGFβ-induced α SM actin expression in cultured cells [11]."[1]

Consensus sequences

The consensus sequence for the TCE in mouse and rat is 5'-GAGTGGGGCG-3' (-117) within the SM22α promoter which extends from -450 to +65 and includes two CArG transcription factors upstream of the TCE.[1]

In mouse and rat SM22α promoters there are 14 nts between the nearest upstream CArG and the TCE, specifically 5'-AGCCTGTGTGGAGT-3'.[1]

"The sequence of the TCE in the human c-myc promoter is [5'-GCGTGGGGGA-3']."[2]

The "TGF-β inhibitory element (TIE [5'-GAGTGGTGA-3']) [is] in the rat transin/stromelysin promoter(12)."[2]

"Robbins et al. (18) have reported that expression of pRB in mouse fibroblasts suppresses transcription of c-fos and have identified an element, termed the retinoblastoma control element (RCE), in the c-fos promoter necessary for this suppression. More recently, sequences homologous to the RCE have been identified in the TGF-β1, -β2, and -β3 promoters by Kim et al. (19)."[2]

"Kim et al. (19) also reported that sequences similar to the RCE are present in the human c-myc promoter".[2]

Human genes

Gene ID: 7040 is TGFB1 transforming growth factor beta 1. "This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate a latency-associated peptide (LAP) and a mature peptide, and is found in either a latent form composed of a mature peptide homodimer, a LAP homodimer, and a latent TGF-beta binding protein, or in an active form consisting solely of the mature peptide homodimer. The mature peptide may also form heterodimers with other TGFB family members. This encoded protein regulates cell proliferation, differentiation and growth, and can modulate expression and activation of other growth factors including interferon gamma and tumor necrosis factor alpha. This gene is frequently upregulated in tumor cells, and mutations in this gene result in Camurati-Engelmann disease."[3]
