Anti-Pax7 (Paired Box Gene 7)

PAX7 is a 57kD member of the paired homeobox family of transcription factors. It is expressed in select neurons (in rodent) and skeletal muscle satellite cells, where, in the latter, it promotes both a muscle stem cell state (PAX7+ desmin-cells) and a lineage commitment state (PAX7+ desmin+ cells). PAX7 forms heterodimers with PAX3, and interacts with the regulatory regions of the Myf5 locus. Human PAX7(A) is 520aa in length. It contains an N-terminal paired box DNA-binding domain (aa34-163), a homeodomain (aa218-275) and a C-terminal poly-alanine region (aa340-346). Multiple splice forms of PAX7 exist. There is a 54kD isoform B that contains a 38aa substitution for aa468-520, plus a second isoform that shows a deletion of Gly151 and Leu152. There is also a chromosomal rearrangement that fuses aa30-385 of PAX7 to aa211-265 of FOXO1A/FKHR. Over aa1-196, human PAX7 shares 86-96aa identity with human PAX3 and mouse PAX7.
