Z. Mourelatos et al., "miRNPs: A novel class of ribonucleoproteins containing numerous microRNAs," Genes & Development, 16[6]:720-8, March 15, 2002. "A novel ribonucleoprotein (RNP) complex in HeLa cells was identified that contains two proteins implicated in spinal muscular atrophy (SMA), eIF2C2 (a member of the Argonaute family), and numerous small RNAs ~22 nucleotides in length. The finding that microRNAs (miRNAs) associate with eIF2C2 ties together genetic findings demonstrating that Argona
