Validation Data Gallery

• 

  WB analysis using 28855-1-AP

  Non-treated PC-3 cells, phosphatase inhibitor treated and λ phosphatase PC-3 cells were subjected to SDS PAGE followed by western blot with 28855-1-AP (Phospho-GYS1 (Ser641) antibody) at dilution of 1:6000 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with GAPDH antibody as loading control.

• 

  IF Staining of PC-3 using 28855-1-AP

  Immunofluorescent analysis of (4% PFA) fixed λ phosphatase treated PC-3 cells using Phospho-GYS1 (Ser641) antibody (28855-1-AP) at dilution of 1:400 and CoraLite®488-Conjugated AffiniPure Goat Anti-Rabbit IgG(H+L) (SA00013-2), CL594-Phalloidin (red).

Background Information

Glycogen synthase 1 (GYS1, GS) catalyzes the key step of glycogen synthesis and plays an important role in glycogen metabolism in liver and muscle. In kidney tissues, glycogen synthase 1 (GYS1) is the most important rate-limiting enzyme functioning in the last step of glycogen synthesis. Pathologically, its deficiency has been shown to cause muscle glycogen storage disease type 0 and death. Studies of tumors showed that GYS1 was rapidly induced under hypoxic conditions and positively correlated with glycogen accumulation in glioblastoma, breast, and colon cancer cell lines. GYS1 is phosphorylated at nine sites and insulin stimulates dephosphorylation of glycogen synthase. Insulin stimulates dephosphorylation of glycogen synthase via PKB-mediated phosphorylation of GSK3. Phosphorylation of GSK3 decreases kinase activity which will decrease phosphorylation of GS and increase glycogens synthase fractional activity. (PMID: 32802186, PMID: 30443599, PMID: 22232606)
