VISTA/B7-H5 Protein is a type I transmembrane protein expressed primarily in white blood cells that inhibits T cell function. VISTA/B7-H5 Protein promotes embryonic stem cell differentiation by inhibiting BMP4 signaling and stimulates MMP14 mediated MMP2 activation. VISTA/B7-H5 Protein is highly expressed in tumors. VISTA/B7-H5 Protein, Mouse (159a.a, HEK293, His) is the recombinant mouse-derived VISTA/B7-H5 protein, expressed by HEK293 , with C-6*His labeled tag.
