Mouse U1 Small Nuclear Ribonucleoprotein 70 kDa, SNRNP70 ELISA Kit, 96T

Component of the spliceosomal U1 snRNP, which is essential for recognition of the pre-mRNA 5' splice-site and the subsequent assembly of the spliceosome. SNRNP70 binds to the loop I region of U1-snRNA. [Isoform 2]: Truncated isoforms that lack the RRM domain cannot bind U1-snRNA.
