cd22508: KH_I_FXR2_rpt2 
second type I K homology (KH) RNA-binding domain found in fragile X mental retardation syndrome-related protein 2 (FXR2) and similar proteins
FXR2, also known as FMR1L2, is an RNA-binding protein that plays a role in central nervous system function. It specifically regulates hippocampal neurogenesis by reducing the stability of Noggin mRNA. FXR2 contains three K-homology (KH) RNA-binding domains. The model corresponds to the second one.

putativeGXXG motif
Feature 1:putative nucleic acid binding site [nucleic acid binding site]
Evidence:
  • Comment:flanked by the GXXG motif and a variable ssRNA/DNA binding loop
  • Comment:Based on the structure evidence that other KH-I superfamily members bind RNA/ssDNA.
