WebMar 12, 2024 · Spliceosomes consist of four different subunits, called small nuclear ribonucleoproteins (snRNP or “snurp”). Each “snurp” has two small nuclear RNAs (snRNAs). These special strands of RNA contain sequences of nucleotides which match specific locations in the exons and bind to them. A spliceosome is a large ribonucleoprotein (RNP) complex found primarily within the nucleus of eukaryotic cells. The spliceosome is assembled from small nuclear RNAs (snRNA) and numerous proteins. Small nuclear RNA (snRNA) molecules bind to specific proteins to form a small nuclear ribonucleoprotein complex (snRNP, pronounced “snurps”), which in turn combines with other snRNPs to fo…
