TWIST2

Twist-related protein 2 is a protein that in humans is encoded by the TWIST2 gene.[5][6][7] The protein encoded by this gene is a basic helix-loop-helix (bHLH) transcription factor and shares similarity with another bHLH transcription factor, TWIST1. Basic helix-loop-helix (bHLH) transcription factors have been implicated in cell lineage determination and differentiation. It is thought that during osteoblast development, this protein may inhibit osteoblast maturation and maintain cells in a preosteoblast phenotype.[7]

Interactions

TWIST2 has been shown to interact with SREBF1.[8]

Clinical significance

Mutations in the TWIST2 gene that alter DNA-binding activity through both dominant-negative and gain-of-function effects are associated with ablepharon macrostomia syndrome and Barber–Say syndrome.[9]
