果蠅胚胎蛋白蝸牛是一種鋅指轉錄抑制因子，下調中胚層外胚層基因的表達。該基因編碼的核蛋白在結構上與果蠅蝸牛蛋白相似，也被認為是發育中胚胎中胚層形成的關鍵。在2號染色體上至少發現了兩個類似的加工假基因變體。[由RefSeq提供，2008年7月]
The Drosophila embryonic protein snail is a zinc finger transcriptional repressor which downregulates the expression of ectodermal genes within the mesoderm. The nuclear protein encoded by this gene is structurally similar to the Drosophila snail protein, and is also thought to be critical for mesoderm formation in the developing embryo. At least two variants of a similar processed pseudogene have been found on chromosome 2. [provided by RefSeq, Jul 2008]
