Transcriptional coactivators potentiating AP-1 function in bone

The AP-1 proteins are formed by the heterodimerization of Fos family members and Jun family members through a structural motif called the leucine zipper. The heterodimer can then bind DNA at a consensus site termed the AP-1 site and act as a transcription factor to modulate the expression of AP-1-responsive genes. All the Jun family members can also homodimerize to exert the same function. Genetic studies including gain-of-function and loss-of-function mutations have shown that AP-1 components,
