ZAN（zonadhesin (gene/pseudogene)），癌症关联基因，基因ID：7455，该基因编码一种蛋白质，在精子粘附卵透明带的物种特异性中发挥作用。编码蛋白位于顶体，可能参与信号传递或配子识别。该基因的等位基因多态性导致功能性和框移等位基因；参考基因组代表功能性等位基因。该基因的选择性剪接导致多个转录变体。[由RefSeq提供，2015年7月]This gene encodes a protein that functions in the species specificity of sperm adhesion to the egg zona pellucida. The encoded protein is located in the acrosome and may be involved in signaling or gamete recognition. An allelic polymorphism in this gene results in both functional and frameshifted alleles; the reference genome represents the functional allele. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq， Jul 2015]。
