Antigène
ITGAV/ITGB8
(Integrin alpha V beta 8 (ITGAV/ITGB8))
Deletions of the genes encoding the integrin αVβ8 (Itgav, Itgb8) have been shown to result in abnormal vascular development in the CNS, including prenatal and perinatal hemorrhage. Other work has indicated that a major function of this integrin in vivo is to promote TGFβ activation.
Poids moléculaire
112.1 kDa (ITGAV)&75.3 kDa (ITGB8). Due to glycosylation, the protein migrates to 90-140 kDa based on Tris-Bis PAGE result.
