SIBLING蛋白是一種非胶原蛋白,是牙本质细胞外基质的组成部分。其英文部分「SIBLING」为小整联N-连接糖蛋白(small integrin-binding ligand, N-linked glycoprotein)的缩写。有证据表明SIBLING蛋白在这些组织的矿化中起关键作用。[1]

下列蛋白质属于SIBLING蛋白:[1][2]

  1. 骨桥蛋白 Osteopontin (OPN) 或分泌磷蛋白1 Secreted phosphoprotein 1 (SPP1);
  2. 骨涎蛋白 bone sialoprotein (BSP);
  3. 牙本质基质蛋白1 Dentin matrix protein 1 (DMP1);
  4. 牙本质唾液酸磷酸蛋白 Dentin sialophosphoprotein (DSPP);
  5. 基质细胞外磷酸糖蛋白 Matrix extracellular phosphoglycoprotein (MEPE)。

编码SIBLING家族蛋白的基因位于人类染色体4q21-23上。[3]
