该基因编码圆锥磷酸二酯酶的α-原亚单位，由两个α-原亚单位的同二聚体和3个11、13和15kDa的小蛋白组成该基因突变与4型锥体营养不良（COD4）有关[由RefSeq提供，2010年3月]
This gene encodes the alpha-prime subunit of cone phosphodiesterase, which is composed of a homodimer of two alpha-prime subunits and 3 smaller proteins of 11, 13, and 15 kDa. Mutations in this gene are associated with cone dystrophy type 4 (COD4). [provided by RefSeq, Mar 2010]
