Activity summary

PAX3 also known as Paired Box 3 is a transcription factor that plays a critical role in embryonic development. It carries a molecular mass of approximately 53 kDa. PAX3 expression occurs mainly in the neural tube somites and limb buds where it regulates gene expression necessary for tissue and organ development. PAX3 protein consists of a paired domain and a homeodomain enabling it to bind DNA and control the expression of target genes. In Australia and abroad researchers often rely on specific PAX3 antibodies to study its presence and role in various biological contexts.

Biological function summary

This protein regulates cell proliferation migration and differentiation within the developing nervous system and skeletal muscles. PAX3 forms part of a complex network that influences various developmental pathways. It works in concert with other transcription factors to ensure proper formation of muscle and neural structures. By modulating these processes PAX3 ensures that tissues develop correctly and function in a coordinated manner.

Pathways

Researchers have identified PAX3’s involvement particularly in the development of neural crest cells and myogenesis. It participates in the Wnt signaling pathway where it interacts with proteins like beta-catenin to drive muscle precursor cell formation. Additionally PAX3 has a critical role in the Notch signaling pathway where it overlaps with the function of other transcription factors like MYOD in regulating muscle differentiation. These interactions highlight PAX3's significance in developmental processes.

Associated diseases and disorders

Mutations in the PAX3 gene have strong associations with Waardenburg syndrome and alveolar rhabdomyosarcoma. In Waardenburg syndrome improper PAX3 function leads to defects in melanocyte differentiation impacting pigmentation and hearing. The connection between PAX3 and alveolar rhabdomyosarcoma involves fusion with the FOXO1 gene forming a chimeric protein that drives oncogenesis. Understanding PAX3’s interactions with other proteins such as MITF in melanocyte function opens avenues for potential therapeutic interventions.
