Anti-PHKG1 / Phosphorylase kinase gamma 1

Adding 0.2 ml of distilled water will yield a concentration of 500 ug/ml. PHKG1 antibody detects Phosphorylase kinase gamma 1, a catalytic subunit of the phosphorylase kinase (PhK) complex that plays a central role in glycogen metabolism. The UniProt recommended name is Phosphorylase kinase gamma 1 (PHKG1). This enzyme functions as a serine/threonine-specific protein kinase responsible for activating glycogen phosphorylase, the enzyme that catalyzes the rate-limiting step in glycogen breakdown. PHKG1 serves as the catalytic component within the multimeric PhK complex, which also includes alpha, beta, and delta subunits that provide regulatory and calcium-binding functions.Phosphorylase kinase gamma 1 is predominantly expressed in skeletal muscle, where it regulates glycogenolysis in response to hormonal and neural stimulation. Activation of the enzyme occurs through phosphorylation and calcium binding, linking it directly to adrenergic and calcium signaling pathways. The PhK complex functions as a molecular bridge between intracellular calcium release and the mobilization of energy reserves during muscle contraction, ensuring that glucose-1-phosphate is made available for rapid ATP production.Structurally, PHKG1 contains conserved kinase domains typical of the protein kinase superfamily, including the ATP-binding site and catalytic loop that mediates phosphate transfer. The gamma 1 isoform differs from the gamma 2 isoform (encoded by PHKG2), which is more abundant in liver tissue, highlighting its tissue-specific regulation. The PHKG1 gene is located on chromosome 7p11.2 and its expression is tightly regulated according to metabolic demand and muscle fiber type.Defects or mutations in PHKG1 can lead to glycogen storage disease type IXd, a rare inherited metabolic disorder characterized by reduced phosphorylase kinase activity, muscle weakness, and exercise intolerance. Because of its key role in energy metabolism, PHKG1 is also investigated in studies of muscle physiology, insulin signaling, and exercise adaptation. Detection of Phosphorylase kinase gamma 1 using PHKG1 antibody allows researchers to monitor enzyme expression, activity, and localization in muscle and metabolic tissues.PHKG1 antibody is useful for applications such as immunohistochemistry, immunofluorescence, and related assays examining kinase regulation and energy metabolism. By identifying the catalytic subunit of phosphorylase kinase, this antibody supports research into glycogen regulation, muscle energy dynamics, and kinase-mediated signaling networks.
