Description
Product Characteristics:
TWIST1 and TWIST2 are basic helix-loop-helix transcriptional repressors that bind to E boxes in gene promoters, acting as master regulators in a variety of biological processes, including organogenesis, osteogenesis, cancer progression and hematopoietic cell development. Both TWIST1 and TWIST2 are found to act as Homodimers or Heterodimers with another bHLH protein. TWIST1 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. TWIST1 also represses expression of proinflammatory cytokines such as TNFA and IL1B. TWIST2 inhibits transcriptional activation by MYOD1, MYOG, MEF2A, and MEF2C. Twist2 inhibits the premature or ectopic differentiation of preosteoblast cells during osteogenesis.

Target Information: Basic helix-loop-helix (bHLH) transcription factors have been implicated in cell lineage determination and differentiation. The protein encoded by this gene is a bHLH transcription factor and shares similarity with another bHLH transcription factor, Twist. It is thought that during osteoblast development this protein may inhibit osteoblast maturation and maintain cells in a preosteoblast phenotype. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Dec 2012]
