Sestavljen je iz kompleksa med [[ribonukleinsko kislino]] in [[proteinom]]. Primeri RNP so npr. [[ribosomi]], encimi [[ribonukleaza P]], [[telomeraza]], [[peptidin telomeraza]], mali [[RNPs]] (snRNP, scRNP),...[http://en.wikipedia.org/wiki/Ribonucleoprotein]<br /> [[snRNP]] ter [[scRNP]] so nov razred ribonukleoproteinskih kompleksov. Nahajajo se v jedru in [[citosolu]] evkariontski celic, kjer se nahaja veliko tipov majhnih RNA molekul, ki imajo manj kot 300 [[nukleotidov]]. Imenujemo jih [[snRNAs]] (majhna jedrna RNAs) in [[scRNAs]] (mala citosolna RNAs,). Te RNA molekule, ki so po velikosti nekje med [[tRNA]] in malo [[mRNA]] 5S, so povezane z specifičnimi proteini in ti tvorijo komplekse imenovane [[snRNPs]] (mali jedrni ribonukleoproteinski delci) in [[scRNPs]] (mali citosolni ribonukleoproteinski delci). [http://www.ncbi.nlm.nih.gov/books/NBK22563/#A4008] Pravimo jim tudi »snurps« ali »scurps«. <br /> <br /> Mali jedrni ribonukleoproteinski delci imajo zelo pomebno vlogo pri zorenju mRNA. Katalizirajo specifične reakcije pri izrezovanju [[intronov]], ki spremenijo genske prepise (heterogeno jedrno RNA) v zrelo mRNA, še preden se ta prenese iz jedra k ribosomom v citosol. Gre za to, da se morajo iz RNA, ki seje prepisala, izraziti nekodirajoča zaporedja (introni), da se kodirajoča ([[eksoni]]) povežejo v aktivno mRNA.[http://www.youtube.com/watch?v=4X8eK15R8yY&amp;feature=related]<br /> <br /> Viri: <br /> <br /> 1. http://en.wikipedia.org/wiki/Ribonucleoprotein<br /> <br /> 2. http://www.ncbi.nlm.nih.gov/books/NBK22563/#A4008<br /> <br /> 3. http://www.youtube.com/watch?v=4X8eK15R8yY&amp;feature=related<br /> <br /> 4.
