该基因编码一个含有类似酵母剪接因子prp40蛋白的ww结构域。该蛋白与Huntingtin和甲基CpG结合蛋白2（MeCP2）相互作用选择性剪接导致不同的转录变体。[由RefSeq提供，2014年8月]
This gene encodes a WW-domain containing protein similar to yeast splicing factor PRP40. This protein has been shown to interact with Huntingtin and methyl CpG binding protein 2 (MeCP2). Alternative splicing results in different transcript variants. [provided by RefSeq, Aug 2014]
