PowerPoint Presentation - Differential regulation of Id1, Id2, andTwist in myogenesis and osteogenesis

Helix Loop Helix Proteins
oVarious helix-loop-helix (HLH) proteins play a key role in theregulation of cellular growth and differentiation
oBasic HLH, bHLH, proteins include a basic DNA binding domain
oMyoD (directs muscle development) and TWIST-1
oHLH proteins lack the basic domain
oId proteins do not bind DNA
