该基因编码的蛋白质是一种rna结合蛋白，与功能相似的fmr1和fxr2蛋白相互作用。这些蛋白质在细胞核和细胞质之间穿梭，与多核糖体相关，主要与60s核糖体亚基相关。已经发现了三个编码不同亚型的转录变体[由RefSeq提供，2008年7月]
The protein encoded by this gene is an RNA binding protein that interacts with the functionally-similar proteins FMR1 and FXR2. These proteins shuttle between the nucleus and cytoplasm and associate with polyribosomes, predominantly with the 60S ribosomal subunit. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
