Atf4 regulates chondrocyte proliferation and differentiation during endochondral ossification by activating <i>Ihh</i> transcription
12 Nov 2009
Abstract excerpt
Activating transcription factor 4 (Atf4) is a leucine-zipper-containing protein of the cAMP response element-binding protein (CREB) family. Ablation of Atf4 (Atf4(-/-)) in mice leads to severe skeletal defects, including delayed ossification and low bone mass, short stature and short limbs. Atf4 is expressed in proliferative and prehypertrophic growth plate chondrocytes, suggesting an autonomous function of Atf4...
