Proteins in this family have been implicated in the assembly of the large subunit of the ribosome [2] and in telomere maintenance [3]. Some proteins in this family contain a CCCH zinc finger. This family contains a protein called human FMR1-interacting protein NUFIP1 which is known to bind RNA [4] and is phosphorylated upon DNA damage [1].
