Master transcription factor of stromal fibroblasts for myofibroblastic lineage progression. Orchestrates the functional drift of fibroblasts into myofibroblastic phenotype via TGF-beta signaling by remodeling a super-enhancer landscape. Through this function, plays an essential role in wound healing process (PubMed:35589735). Acts as a transcriptional regulator of muscle creatine kinase (MCK) and so has a role in the establishment of diverse mesodermal muscle types. The protein binds to an A/T-rich element in the muscle creatine enhancer (By similarity). May play a role in homeostasis and regeneration of bone, white adipose tissue and derm (By similarity). . [Isoform 1]: Transcriptional activator, when transfected in fibroblastic or myoblastic cell lines. This activity may be masked by the C-terminal OAR domain. . [Isoform 2]: Transcriptional repressor, when transfected in fibroblastic or myoblastic cell lines. . This is the function of PRRX1 (paired related homeobox 1, ENSG00000116132).
