InterPro domain: IPR034823

This entry represents the RNA recognition motif 1 (RRM1) domains found in A. thaliana CID8, CID9, CID10, CID11, CID12, CID 13 and mainly their plant homologues [ 1 , 2 ]. These highly related RNA-binding proteins contain an N-terminal PAM2 domain (PABP-interacting motif 2), two RNA recognition motifs (RRMs) and a basic region that resembles a bipartite nuclear localization signal. The biological role of this family remains unclear.
