该基因编码类虾青素锌依赖性金属蛋白酶，是metzincin家族的一个亚家族成员。与其他家族成员不同的是，小鼠体内的一种类似蛋白质不会分解前胶原C-前肽或氯丁[由RefSeq提供，2008年7月]
This gene encodes an astacin-like zinc-dependent metalloprotease and is a subfamily member of the metzincin family. Unlike other family members, a similar protein in mice does not cleave procollagen C-propeptides or chordin. [provided by RefSeq, Jul 2008]
