ribonucleoprotein

ribonucleoprotein
Complexes of RNA and protein involved in a wide range of cellular processes. Besides ribosomes (with which RNP was originally almost synonymous), in eukaryotic cells both initial RNA transcripts in the nucleus (hnRNA) and cytoplasmic mRNAs exist as complexes with specific sets of proteins. Processing (splicing) of the former is carried out by small nuclear RNPs (snRNPs). Other examples are the signal recognition particle responsible for targeting proteins to endoplasmic reticulum and a complex involved in termination of transcription.
