Hyaluronic Acid Receptor (HA Receptor)

Target: HA Receptor
Molecular classification: Receptor, Transmembrane Protein, Glycoprotein

Overview

The term "hyaluronic acid receptor" refers to a group of cell surface proteins that specifically bind hyaluronic acid (HA). These receptors mediate diverse biological processes, including cell adhesion, migration, proliferation, inflammation, tissue repair, and tumor progression. Major HA receptors include CD44, RHAMM, LYVE-1, HARE/Stabilin-2, Layilin, and TLR4. Binding of HA to these receptors initiates intracellular signaling cascades affecting gene expression and cellular behavior. Alterations in HA receptor expression or function are associated with various diseases, including cancer and inflammatory disorders.

Other names: Hyaluronan ReceptorHA Binding Protein

Mechanism of action

HA binding initiates intracellular signaling cascades affecting gene expression related to inflammation response, cytoskeletal rearrangement/motility, survival/apoptosis pathways.
