The bone morphogenetic protein (BMP) 1/tolloid (TLD) proteinase family is a group of important metalloproteinases, which play key roles in the growth and development of tissues and organs via regulating the biosynthetic processing of the extracellular matrix. Clinical reports have revealed that mutations in the genes encoding BMP1/TLD proteinases lead to dentinogenesis imperfecta type Ⅰ, accompanied with osteogenesis imperfecta. Therefore, this proteinase family is essential for the development of hard tissues. In this study, we review the research progress in the function and mechanism of the BMP1/TLD proteinase family in the development of teeth and bone.
骨形态发生蛋白（BMP）1/tolloid（TLD）蛋白酶家族是一类重要的基质金属蛋白酶，可通过调控细胞外基质的生物合成而在组织、器官生长发育中发挥重要作用。临床报道发现BMP1/TLD蛋白酶家族的编码基因发生突变可导致伴有成骨发育不全的Ⅰ型牙本质发育不全，提示该蛋白酶家族在牙及骨等硬组织发育中具有重要作用。本文将BMP1/TLD蛋白酶家族在牙和骨组织发育中的作用及其机制所取得的研究进展作一综述。.
