Q15672 TWST1_HUMAN:

Subset of mesodermal cells.

描述:
Acts as a transcriptional regulator. Inhibits myogenesis by sequestrating E proteins, inhibiting trans-activation by MEF2, and inhibiting DNA-binding by MYOD1 through physical interaction. This interaction probably involves the basic domains of both proteins. Also represses expression of proinflammatory cytokines such as TNFA and IL1B. Regulates cranial suture patterning and fusion. Activates transcription as a heterodimer with E proteins. Regulates gene expression differentially, depending on dimer composition. Homodimers induce expression of FGFR2 and POSTN while heterodimers repress FGFR2 and POSTN expression and induce THBS1 expression. Heterodimerization is also required for osteoblast differentiation.

研究背景

功能:

Acts as a transcriptional regulator. Inhibits myogenesis by sequestrating E proteins, inhibiting trans-activation by MEF2, and inhibiting DNA-binding by MYOD1 through physical interaction. This interaction probably involves the basic domains of both proteins. Also represses expression of proinflammatory cytokines such as TNFA and IL1B. Regulates cranial suture patterning and fusion. Activates transcription as a heterodimer with E proteins. Regulates gene expression differentially, depending on dimer composition. Homodimers induce expression of FGFR2 and POSTN while heterodimers repress FGFR2 and POSTN expression and induce THBS1 expression. Heterodimerization is also required for osteoblast differentiation. Represses the activity of the circadian transcriptional activator: NPAS2-ARNTL/BMAL1 heterodimer (By similarity).

组织特异性:

Subset of mesodermal cells.

亚基结构:

Efficient DNA binding requires dimerization with another bHLH protein. Homodimer or heterodimer with E proteins such as TCF3. ID1 binds preferentially to TCF3 but does not interact efficiently with TWIST1 so ID1 levels control the amount of TCF3 available to dimerize with TWIST1 and thus determine the type of dimer formed (By similarity).

Application: WB    Species: human    Sample: A549 cells

Figure 3. A549/DDP and A549/PTX cells showed molecular and morphological changes that were consistent with EMT. (A) microscopy at x200 magnification was used to assess cell morphology. The A549 cells (parental cells) had an epithelioid, rounded cobblestone appearance and there was limited formation of pseudopodia. A549/PTX and A549/DDP cells exhibited a spindle-shaped morphology and an increased formation of pseudopodia, indicating a loss of cell polarity. (B) E-cadherin, β-catenin, vimentin, MMP-2 and MMP-9 which are EMT-related proteins, were assessed in terms of expression levels. EMT-related transcription factors (Snail, Slug, Twist and ZEB1) were measured in A549/PTX and A549/DDP cells using western blot analysis. (C) The expression changes were confirmed at the mRNA level by qRT-PCR. Expression was standardized to the expression of GAPDH and normalized to 1.0 in the parental cells (compared with the parental A549 cells, means ± SEM, n=3, * P<0.05)
