Gene Information

human ... PHKA1P1(646780)

General description

The gene PHKA1 (phosphorylase kinase, α 1) encodes the skeletal muscle isoform of the α subunit of phosphorylase kinase. This enzyme is a hexadekameric protein with 16 subunits containing four each of α, β, γ and δ. The gene is mapped to chromosome X in humans.

Immunogen

Phosphorylase b kinase regulatory subunit-α, skeletal muscle isoform recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

The hexadekameric complex of phosphorylase kinase (Phk) is involved in the regulation of glycogen breakdown by phosphorylation of glycogen phosphorylase. Mutation in the PHKA1 (phosphorylase kinase, α 1) gene can cause a deficiency of Phk leading to glycogen storage diseases or muscle-specific glycogenosis. This is characterized by exercise intolerance with early fatigue, pain, cramps and rarely myoglobinuria.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

Heritable phosphorylase kinase (Phk) deficiency underlies a group of glycogenoses in humans, mice and rats that differ in mode of inheritance and tissue-specificity. It is assumed that this heterogeneity is caused by mutations affecting different subunits and isoforms of Phk.
