GlycoFlux™ Human PTGER4 Overexpression HEK293T Cell Line (CAT#: GLJF-0925-JF593)

Description	GlycoFlux™ human PTGER4 overexpression HEK293T cell line is a stable glycoengineered line that constitutively overexpresses EP4 (PTGER4), a PGE₂ GPCR that drives TCF signaling and GSK3 phosphorylation. This model is suited for ligand-bias screens with glyco-readouts, quantifying how GPCR tone reshapes sialyl-Lewis antigen expression, receptor internalization, and immune-modulatory glycoepitopes.

Handling Notes	Upon receipt, this product must be immediately transferred from dry ice to liquid nitrogen (-150°C to -190°C) and stored in a liquid nitrogen tank. Cell viability is critically dependent on proper handling. We cannot guarantee viability if these instructions are not strictly adhered to.
Product Disclaimer	This product is provided for research only, not suitable for human or animal use. Due to the inherent limitations of infectious agent testing, investigators must exercise extreme caution when handling cells provided by Creative Biolabs, treating all cells as potentially biohazardous.

Target	PTGER4
Full Name	Prostaglandin E Receptor 4
Alternative Name	EP4; EP4R
Location	5p13.1
Gene ID	5734
Summary	This gene encodes a G-protein coupled receptor that is one of four receptors for prostaglandin E2 (PGE2). It triggers T-cell factor signaling, drives PGE2-mediated EGR1 expression, influences cyclooxygenase-2 mRNA turnover, and induces phosphorylation of glycogen synthase kinase-3. Mouse Overexpression models indicate roles in newborn cardiovascular adjustment, bone density regulation, and initiation of cutaneous immune defense.
