这个基因编码的蛋白质是视网膜间感受器基质的主要成分。编码蛋白是一种蛋白多糖，被认为在维持感光细胞的活力和神经视网膜与视网膜色素上皮的粘附中起作用。交替剪接导致多个转录变体。[由RefSeq提供，2013年9月]
This gene encodes a protein that is a major component of the retinal interphotoreceptor matrix. The encoded protein is a proteoglycan that is thought to play a role in maintaining viability of photoreceptor cells and in adhesion of the neural retina to the retinal pigment epithelium. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
