PossCSPG1 (or possibly CSPG1) refers to a gene that encodes a protein known as chondroitin sulfate proteoglycan 1. This protein is involved in various cellular processes, including cell adhesion, migration, and signaling. It plays a significant role in the extracellular matrix and is associated with development and tissue repair. Additionally, alterations in CSPG1 expression have been linked to certain diseases, including cancer and neurodegenerative disorders.
