  • 免疫原

    Human Muscle Glycogen Synthase (GYS1) phospho peptide corresponding to a region of the human protein conjugated to Keyhole Limpet Hemocyanin (KLH) - AQGYRYPRPA(pS)VP (aa 631-642).

  • 常规说明

    Human muscle glycogen synthase (GYS1) is responsible for the biosynthesis of glycogen from phosphorylated glucose units. Mammalian liver and muscle contain GS consisting of four subunits with a total molecular weight of 360,000. GS is subject to regulation through both allosteric and covalent modification and occurs in two forms: the phosphorylated inactive form, and the dephosphorylated active form. GYS1 is inactivated by the serine/threonine kinase called glycogen synthase kinase-3b that mainly functions to phosphorylate muscle glycogen synthase. This antibody is specific for the phosphorylated form of GYS1 at Ser 640. Phosphorylation of GYS1 at S640 has been associated with Antiphospholipid Antibody Syndrome.

Although not tested, this antibody is likely functional in Immunohistochemistry and Immunoprecipitation.


  • 功能
    Transfers the glycosyl residue from UDP-Glc to the non-reducing end of alpha-1,4-glucan.
  • 通路
    Glycan biosynthesis; glycogen biosynthesis.
  • 疾病相关
    Defects in GYS1 are the cause of muscle glycogen storage disease type 0 (GSD0b) [MIM:611556]; also known as muscle glycogen synthase deficiency. GSD0b is a metabolic disorder characterized by fasting hypoglycemia presenting in infancy or early childhood. The role of muscle glycogen is to provide critical energy during bursts of activity and sustained muscle work.
  • 序列相似性
    Belongs to the glycosyltransferase 3 family.

    Rabbit polyclonal to phospho Glycogen Synthase (Ser 640) used at a 1/1000 dilution to detect human muscle GS by Western blot.  Approximately 12 ul of a mouse cardiac myocyte lysate was loaded per lane on a 4-20% Criterion gel for SDS-PAGE.  Samples were either mock treated (lanes 1 and 5) or insulin treated at 10 nM, 100 nM and 1 mM (lanes 2, 3 and 4 respectively) for 15' or CLA treated at 4nM, 20 nM or 100 nM (lanes 6,7 and 8 respectively) for 45'. 

    Goat polyclonal to rabbit IgG (HRP) (ab7090) was used as secondary antibody at 1/5000.

    A 4-20% Criterion gel for SDS-PAGE was used.
