Target Details

Target: GDF15 (Growth Differentiation Factor 15 (GDF15))

Alternative Name: GDF15

Background: Growth Differentiation Factor 15 (GDF15), also known as NSAID activated gene-1 (NAG-1), is associated with a large number of biological processes and diseases, including cancer and obesity. GDF15 is synthesized as pro-GDF15, is dimerized, and is cleaved and secreted into the circulation as a mature dimer GDF15.

Molecular Weight: 13.5 kDa. The protein migrates to 15-16 kDa based on Tris-Bis PAGE result.

UniProt: Q99988-1

Pathways: SARS-CoV-2 Protein Interactome
