Abstract
Here we report the identification of two transglutaminase-reactive glutamines (Gln-34 and Gln-36) in bovine osteopontin (OPN). Sequence alignment revealed that these glutamines are conserved in all known OPN sequences, indicating a functional importance of this region of the protein. Furthermore, immunological analysis of bovine bone demonstrated that OPN is present in high-molecular-mass complexes in vivo. These findings support the functional aspects of a transglutaminase-catalysed cross-linking of OPN in facilitating cellular attachment and tissue calcification.Entities:
