PAX7. a member of the paired box (PAX) family of transcription factors, plays a critical role in regulating skeletal muscle development and satellite cell biology. The PAX family consists of nine genes (PAX1–PAX9) categorized by their conserved DNA-binding paired domains, which enable sequence-specific interactions with target genes. PAX7. specifically, is essential for the specification, proliferation, and maintenance of muscle satellite cells—adult stem cells responsible for postnatal muscle growth, repair, and regeneration. During embryogenesis, PAX7 expression marks muscle progenitor cells, guiding their migration and differentiation. Postnatally, it ensures the self-renewal of satellite cells while preventing premature differentiation.
Recombinant human PAX7 protein is engineered using biotechnological systems (e.g., E. coli or mammalian cell cultures) to produce functional PAX7 for research and therapeutic applications. Its structure typically retains key domains, including the N-terminal paired domain for DNA binding and a transactivation domain for regulating gene expression. Studies leveraging recombinant PAX7 have advanced understanding of muscle regeneration mechanisms, muscular dystrophies, and cancer (e.g., rhabdomyosarcoma). Additionally, it holds potential in cell-based therapies to restore muscle function in degenerative diseases. Its role in maintaining stem cell quiescence and activating myogenic programs underscores its biomedical significance, driving ongoing exploration in regenerative medicine and disease modeling.
