Sujet
B7-H7, also known as HHLA2 (HERV-H LTR-associating 2), is a member of the B7 family of immune regulatory proteins.Through interaction with TMIGD2, costimulates T-cells in the context of TCR-mediated activation. Enhances T-cell proliferation and cytokine production via an AKT-dependent signaling cascade.
Poids moléculaire
63.7 kDa. Due to glycosylation, the protein migrates to 78-100 kDa based on Tris-Bis PAGE result.
