Target Details

Target: CSF2RA (Colony Stimulating Factor 2 Receptor, Alpha, Low-Affinity (Granulocyte-Macrophage) (CSF2RA))

Alternative Name: GM-CSF R alpha (CSF2RA Products)

Background: In the first trimester, the GM-CSF-R was found to be present on villous cytotrophoblast and all populations of extravillous trophoblast. Expression by villous syncytiotrophoblast was weak or absent, but this increased markedly by term. GM-CSF-R were also expressed by fetal Hofbauer cells within the mesenchyme of the chorionic villi and by uterine glandular epithelium and decidual macrophages within maternal decidua.

Molecular Weight: 35.3 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result.

Pathways: JAK-STAT Signaling
