Immunofluorescent analysis of PAX7 in MCF7 (left panel) and HeLa (right panel) cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature. Cells were probed with a ab187339 at 1/100 dilution for at least 1 hour at room temperature, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-rabbit IgG secondary antibody at 1/400 dilution for 30 minutes at room temperature. F-Actin (red) was stained with DyLight-554 Phalloidin and nuclei (blue) were stained with Hoechst 33342 dye.

Immunoprecipitation - Anti-PAX7 antibody (AB187339)

Immunoprecipitation of PAX7 was performed using HeLa whole cell lysate. Antigen-antibody complexes were formed by incubating 500μg of lysate with 3μg of ab187339 overnight on a rocking platform at 4°C. The immune complexes were captured on 50ul Protein A/G Agarose, washed extensively, and eluted. Samples was resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBS-0.1%Tween-20 for 1 hour. The membrane was probed with ab187339 at 1/1000 dilution overnight rotating at 4°C.

Specificity

<p>Western blot analysis of ab187339 detects a prominent ~54 kDa protein in human HeLa, MCF7, rhabdomyosarcoma and skeletal muscle satellite cells and a weaker ~57 kDa protein in HeLa, rhabdomyosarcoma and skeletal muscle satellite cells. The ~57 kDa band seems to be enriched in immunoprecipitations from HeLa lysate, suggesting a bias for the larger isoform in ths application.</p>

Supplementary information

PAX7 or paired box 7 is a member of the paired box (PAX) family of transcription factors. Alternative names for PAX7 include PAX7 protein and PAX7 FACS. This protein has a molecular weight of approximately 57 kDa. PAX7 is mainly expressed in muscle precursor cells where it plays an important role in regulating muscle development. Researchers commonly detect it through PAX7 staining techniques in laboratory settings.
Biological function summary

PAX7 functions are important for muscle cell proliferation and differentiation. It works within a transcriptional complex where it partners with other proteins to promote satellite cell maintenance. Satellite cells are essential for muscle regeneration and PAX7 regulates their self-renewal and differentiation. The protein also modulates various genetic targets that affect the muscle cellular environment ensuring proper muscle function and repair.

Pathways

PAX7 is involved in the myogenic regulatory pathways that guide muscle development and regeneration. It interacts with important proteins like MyoD and Myf5 to influence these processes. These pathways facilitate the conversion of satellite cells into mature muscle fibers important during muscle growth and healing. PAX7’s function in these pathways ensures satellite cells remain active and capable of muscle repair throughout an organism's life.

PAX7’s dysfunction can lead to muscle-related conditions such as rhabdomyosarcoma and certain muscle dystrophies. In rhabdomyosarcoma improper regulation of PAX7 leads to unchecked cellular proliferation contributing to tumor growth. This disorder links PAX7 to other proteins in the tumorigenic pathway such as PAX3 which similarly influences muscle cell behavior in pathological states. Identifying PAX7 alterations can guide diagnosis and therapeutic strategies in muscle-associated disorders.
