The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface glycoprotein found in the outer segment of both rod and cone photoreceptor cells. It may function as an adhesion molecule involved in stabilization and compaction of outer segment disks or in the maintenance of the curvature of the rim. This protein is essential for disk morphogenesis. Defects in this gene are associated with both central and peripheral retinal degenerations. Some of the various phenotypically different disorders are autosomal dominant retinitis pigmentosa, progressive macular degeneration, macular dystrophy and retinitis pigmentosa digenic.

[中文简述(自动翻译):]  由该基因编码的蛋白是跨膜4超家族的成员,也称为四旋家族。大多数这些成员是细胞表面蛋白质的特征在于四个疏水区的存在。蛋白质介导其在细胞发育,活化,生长和运动的调节作用的信号转导事件。这个编码的蛋白是在这两个杆和视锥感光细胞外节中发现的细胞表面糖蛋白。它可以如参与外段磁盘稳定和压实或在维持轮圈的曲率的粘附分子的作用。这种蛋白是盘形态发生是至关重要的。在这个基因的缺陷与中枢和外周视网膜变性有关。一些不同的表型的不同失调的是常染色体显性遗传视网膜色素变性,渐进性黄斑变性,黄斑营养不良和视网膜色素变性digenic。 [由RefSeq的,2008年7月提供]
