FXR2Fragile X mental retardation syndrome-related protein 2 is a protein that in humans is encoded by the FXR2 gene.FunctionThe protein encoded by this gene is an RNA-binding protein containing two KH domains and one RCG box, similar to FMRP and FXR1. It associates with polyribosomes, predominantly with 60S large ribosomal subunits. This protein may self-associate or interact with FMRP and FXR1. It may play a role in the development of fragile X mental retardation syndrome.InteractionsFXR2 has been shown to interact with: CYFIP2, FMR1, FXR1, and LCMT1.
