该基因编码的蛋白质属于NALP蛋白家族NALP蛋白家族成员通常包含NACHT结构域、NACHT相关结构域（NAD）、C末端富含亮氨酸重复序列（LRR）区域和N末端吡喃结构域（PYD）。这种基因的表达仅限于卵母细胞一种小鼠基因，编码母细胞蛋白，类似于这种编码蛋白，是正常早期胚胎发生所必需的。[由RefSeq提供，2008年7月]
The protein encoded by this gene belongs to the NALP protein family. Members of the NALP protein family typically contain a NACHT domain, a NACHT-associated domain (NAD), a C-terminal leucine-rich repeat (LRR) region, and an N-terminal pyrin domain (PYD). Expression of this gene is restricted to the oocyte. A mouse gene that encodes a maternal oocyte protein, similar to this encoded protein, is required for normal early embryogenesis.
