Phospho-PLC‑ gamma 1 (Y783) in A431 Human Cell Line. PLC‑ gamma 1 phosphorylated at Y783 was detected in immersion fixed A431 human epithelial carcinoma cell line treated with Recombinant Human EGF (Catalog # 236-EG) using Rabbit Anti-Human Phospho-PLC‑ gamma 1 (Y783) Polyclonal Antibody (Catalog # MAB74542) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; Catalog # NL004) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and plasma membranes. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: PLC-gamma 1
Phospholipase C gamma-1 (PLC-gamma 1) is activated by receptor tyrosine kinases in response to growth factors and hormones, and phosphorylation at Tyr783 is a widely used indicator of activation. Activated PLC-gamma 1 catalyzes the hydrolysis of phosphatidylinositol 4,5-biphosphate to produce the second messengers inositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG). IP3 mobilizes the release of calcium while DAG activates protein kinase C. PLC-gamma 1 plays an important role in regulating cell proliferation and differentiation.
