Recombinant Human RNA-binding protein 40 (RNPC3)

Uniprot Id

Q96LT9

Target Species

Human

Target Name

RNPC3

Target Full Name

RNA-binding region-containing protein 3

Target Function

Participates in pre-mRNA U12-dependent splicing, performed by the minor spliceosome which removes U12-type introns. U12-type introns comprises less than 1% of all non-coding sequences. Binds to the 3'-stem-loop of m(7)G-capped U12 snRNA.

Target Subcellular Location

Nucleus.

Target Tissue Specificity

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.

Target Synonyms

RNPC3; KIAA1839; RBM40; RNP; SNRNP65; RNA-binding region-containing protein 3; RNA-binding motif protein 40; RNA-binding protein 40; U11/U12 small nuclear ribonucleoprotein 65 kDa protein; U11/U12 snRNP 65 kDa protein; U11/U12-65K

Target Background

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. This gene 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.
