U1 small nuclear ribonucleoprotein 70 kDa (SNRNP70)

Part of the spliceosomal U1 snRNP, which is essential for comprehension of the pre-mRNA 5' splice-site and the subsequent assembly of the spliceosome (PubMed:19325628, PubMed:25555158). SNRNP70 binds to the loop that I region of U1-snRNA (PubMed:2467746, PubMed:19325628, PubMed:25555158).
