  • Function

    Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties.
  • Involvement in disease

    Defects in PYGM are the cause of glycogen storage disease type 5 (GSD5) [MIM:232600]; also known as McArdle disease. GSD5 is a metabolic disorder resulting in myopathy characterized by exercise intolerance, cramps, muscle weakness and recurrent myoglobinuria.
  • Sequence similarities

    Belongs to the glycogen phosphorylase family.
  • Post-translational

    Phosphorylation of Ser-15 converts phosphorylase B (unphosphorylated) to phosphorylase A.

Customer reviews and Q&As


Thank you for your enquiry and your interest in our products.
The homology between mouse and human seems to be very high (above 95%) so cross-reactivity with murine PYGM can be expected even for those two antibodies (ab63158 and ab63159) which have not been tested in mouse.
The other antibody (ab88078) has been tested for cross-reaction with mouse but it has not been characterized for immunocyto/histochemistry. Since the host species is mouse, it may well be that non-specific high background could be a technical issue.
