PAX7 Antibody

The PAX gene family of nuclear transcription factors is comprised of nine members that function during embryogenesis to regulate the temporal and position-dependent differentiation of cells. In addition, the family is involved in a variety of signal transduction pathways in the adult organism. Mutations in the PAX family of proteins have been linked to disease and cancer in humans. PAX7 is a protein specifically expressed in cultured satellite cell- derived myoblasts. In situ hybridization reveals that PAX7 is also expressed in satellite cells residing in adult muscle. A chromosomal aberration in the gene encoding PAX7 causes rhabdomyosarcoma 2 (RMS2) (also called alveolar rhabdomyosarcoma).
