hnrnp: hetrogenenous nuclear ribonucleoprotein The hnrNa is rapidly covered in proteins to form hnrnp The proteins involved have been classified as hnrNa proteins A-U These proteins are organized as a tetramer. Three copies of tetramer are combined with a RNa molecule of 600-700nt, called hnrNP particles, each particle has a size of 30-40S三、hnRNP : hetrogenenous nuclear ribonucleoprotein The hnRNA is rapidly covered in proteins to form hnRNP.
