近年来

In recent years, much work on the characteristics of gene, protein structure and expression has been done. Up to now, people have gained considerable knowledge about the AMBN gene series of mouse, rat, pig, human and caiman, and the expression pattern of AMBN protein and mRNA. However, many problems about this protein remain unsolved yet.

近年来，不少学者在AMBN的基因特征、蛋白结构和功能、组织定位等方面展开了深入的研究，先后克隆了小鼠、大鼠、猪、人和鳄鱼等的基因序列，用免疫组化或原位杂交方法对部分种属的动物和人的AMBN或AMBN mRNA的表达进行了时空定位，并在此基础上对蛋白的功能作了初步研究。
