His experimentation with the green algae Acetabularia provided a model subject for modern cell biological research, and proved the existence of morphogenetic substances, or mRNP.
Proteins containing a B-box zinc finger domain include transcription factors, ribonucleoproteins and proto-oncoproteins; for example, MID1, MID2, TRIM9, TNL, TRIM36, TRIM63, TRIFIC, NCL1 and CONSTANS-like proteins.
The minor spliceosome is a ribonucleoprotein complex that catalyses the removal (splicing) of an atypical class of spliceosomal introns (U12-type) from eukaryotic messenger RNAs in plant, insects, vertebrates and some fungi (Rhizopus oryzae).
Small nuclear ribonucleoprotein polypeptide A has been shown to interact with CDC5L.
Small nuclear ribonucleoprotein polypeptide C has been shown to interact with Ewing sarcoma breakpoint region 1.
