Détail du produit

Attributs du protein: BoxA

Fonction: BoxA is one of the highly conserved DNA binding domains of HMGB1 protein (HMG boxes), and inhibits HMGB1 effects in vivo.

Séquence: BoxA from HMGB1 consists of 89 amino acid: MGKGDPKKPR GKMSSYAFFV QTCREEHKKK HPDASVNFSE FSKKCSERWK TMSAKEKGKF EDMAKADKAR YEREMKTYIP PKGETKKKF

Attributs du produit: The BoxA we provide has no difference from the sequence of the human or mouse HMGB1, and as a self-antigen elicits very low immunological responses.
BoxA protects against sepsis in a mouse peritonitis model (Yang et al. 2004), and from hepatitis in a mouse model of HBV infection (Sitia et al. 2007).
Dendritic cells promote their own maturation and T cell proliferation, survival and Th1 differentiation by secreting HMGB1, and BoxA inhibits these activities (Dumitriu et al. 2005).
BoxA also inhibits the chemotactic activity of HMGB1 and the mitogenic activity of HMGB1 on stem cells.
BoxA from HMGB1 is produced in E.coli from an expression plasmid coding for the unmodified mammalian sequence, which is totally identical in human and mouse.
