Sheep

Recognizes human TWIST1.

Purified
Purified by ammonium sulfate precipitation.

Supplied as a liquid in 1ml saline, 0.5% BSA, 0.1% sodium azide. Labeled with Allophycocyanin (APC).

May be stored at 4 degree C before opening. DO NOT FREEZE! Stable at 4 degree C as an undiluted liquid. Dilute only prior to immediate use. Stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. Freezing APC conjugates will result in a substantial loss of activity. APC conjugates are sensitive to light.

Small volumes of anti-TWIST1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

TWST1_HUMAN

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, Dermo1. The strongest expression of this mRNA is in placental tissue; in *****s, mesodermally derived tissues express this mRNA preferentially. Mutations in this gene have been found in patients with Saethre-Chotzen syndrome. [provided by RefSeq]

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. 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. 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.
