Paired box protein 7; This domain family is found in eukaryotes, and is approximately 40 amino acids in length. The family is found in association with pfam00046, pfam00292. Pax7 belongs to a family of genes that encode paired-box-containing transcription factors involved in the control of developmental processes. Pax7 has a distinct role in the specification of myogenic satellite cells.

Paired box protein 7; This domain family is found in eukaryotes, and is approximately 40 amino acids in length. The family is found in association with pfam00046, pfam00292. Pax7 belongs to a family of genes that encode paired-box-containing transcription factors involved in the control of developmental processes. Pax7 has a distinct role in the specification of myogenic satellite cells.
