Background Information

Twist-related protein 1 (TWIST1), also named as BHLHA38, is 202 amino acid protein, which contains one bHLH domain. TWIST1 localizes in the nucleus and acts as a transcriptional regulator. TWIST1 inhibits monogenesis by sequestrating E proteins and inhibits tans-activation by MEF2. TWIST1 is expressed in subset of mesodermal cells. The antibody reacts specifically with Twist1 protein. The calculated molecular weight of TWIST1 is 21 kDa, but the observed molecular weight is about 30 kDa due to the post-translational modification(PMID: 30733340).
