RNA recognition motif (RRM) found in vertebrate RNA-binding protein Raly This subgroup corresponds to the RRM of Raly, also termed autoantigen p542, or heterogeneous nuclear ribonucleoprotein C-like 2, or hnRNP core protein C-like 2, or hnRNP associated with lethal yellow protein homolog, an RNA-binding protein that may play a critical role in embryonic development. It is encoded by Raly, a ubiquitously expressed gene of unknown function. Raly shows a high degree of identity with the 5' sequences of p542 gene encoding autoantigen, which can cross-react with EBNA-1 of the Epstein Barr virus. Raly contains two distinct domains, an N-terminal RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), and a C-terminal auxiliary domain that includes a unique glycine/serine-rich stretch.
