RNA recognition motif 2 (RRM2) found in vertebrate RNA-binding protein 46 (RBM46) This subgroup corresponds to the RRM2 of RBM46, also termed cancer/testis antigen 68 (CT68). It is a putative RNA-binding protein that shows high sequence homology with heterogeneous nuclear ribonucleoprotein R (hnRNP R) and heterogeneous nuclear ribonucleoprotein Q (hnRNP Q). Its biological function remains unclear. Like hnRNP R and hnRNP Q, RBM46 contains two well-defined and one degenerated RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains). |
