RNA Binding Region Containing Protein 3 (RNPC3)

Two types of spliceosomes catalyze splicing of pre-mRNAs. The major U2-type spliceosome is found in all eukaryotes and removes U2-type introns, which represent more than 99% of pre-mRNA introns. The minor U12-type spliceosome is found in some eukaryotes and removes U12-type introns, which are rare and have distinct splice consensus signals. The U12-type spliceosome consists of several small nuclear RNAs and associated proteins. RNPC3 encodes a 65K protein that is a component of the U12-type spliceosome. This protein contains two RNA recognition motifs (RRMs), suggesting that it may contact one of the small nuclear RNAs of the minor spliceosome.Highly expressed in pancreas and kidney. Detected at lower levels in heart, brain, placenta, lung, liver, spleen, thymus, prostate, testis, ovary, small intestine, colon and leukocytes.
