hnRNP C1 + C2 Proteins and Enzymes

RNA polymerase II transcripts in the nucleus are in complex with several proteins called heterogeneous nuclear ribonucleoproteins (hnRNPs). These proteins are important in biological activities such as transcription, pre-mRNA processing, cytoplasmic mRNA translation, and turnover. hnRNPs can be isolated either by immunoprecipitation or by sucrose gradient fractionation of cell extracts. When this is performed, the hnRNPs are isolated (consisting of protein groups named A to U), and many of ...
