Product Detail	FMR2 is a 1311 amino acid nuclear protein belonging to the AF4 family. Expressed in the brain, placenta and lung, FMR2 exists as two isoforms produced by alternative splicing. Defects in the gene that encodes FMR2 have been found to be a cause of FRAXE, an X-linked form of mental retardation. Individuals expressing the FRAXE site also have more than two-hundred copies of a GCC repeat adjacent to CpG island, compared to six to thirty-five copies of the GCC repeat in a normal individual. It is believed that loss of FMR2 expression causes this GCC expansion of the FRAXE site. Function: RNA-binding protein. Might be involved in alternative splicing regulation through an interaction with G-quartet RNA structure. Subcellular Location: Nucleus speckle. When splicing is inhibited, accumlates in enlarged speckles. Tissue Specificity: Brain (most abundant in hippocampus and amygdala), placenta and lung. DISEASE: Defects in AFF2 are the cause of fragile X-E mental retardation syndrome (FRAXE) [MIM:309548]. FRAXE is an X-linked form of mental retardation. Loss of FMR2 expression is correlated with FRAXE CCG(N) expansion. Normal individuals have 6-35 copies of the repeat, whereas cytogenetically positive, developmentally delayed males have more than 200 copies and show methylation of the associated CPG island. Similarity: Belongs to the AF4 family.
