Twist-related protein 2 is a protein that in humans is encoded by the TWIST2 gene.^[1][2][3]

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.^[3]

Interactions

TWIST2 has been shown to interact with SREBF1.^[4]
