Anti-phospho Pax3, Ser201 [6A4E9] Antibody

This rat monoclonal antibody recognizes human and mouse Pax3 and its associated oncogenic fusion protein Pax3-FOXO1 only when specifically phosphorylated at Ser201.

Pax3 is a developmentally regulated transcription factor that is expressed in tissues associated with the central nervous system, craniofacial trunk, trunk neural crest, somites and skeletal muscle. Pax3 has been implicated in melanoma. Additionally, in alveolar rhabdomyosarcoma (ARMS), Pax3 is fused to the transcription factor FOXO1 to form the oncogenic fusion protein Pax3-FOXO1. Protein phosphorylation by GSK3ß at Ser201 has been implicated in the biological activity of Pax3 and the oncogenic potential of Pax3-FOXO1, making this antibody useful for studying these cancers as well as nerve and muscle development and differentiation.

Data

Representative antibody recognition of Pax3(p201) by Western Blot

Pax3 WB

Bacterially expressed and purified wild-type GST-Pax3 was used as purified (left lanes) or was phosphorylated using an in vitro kinase assay and non-radioactive ATP (right lanes). The proteins were used for Western blot analysis using the anti-Pax3(p201) polyclonal antibody. A Coomassie stained gel demonstrates the presence of equal amounts of protein in the assay (top panel).
