An important paralog of this gene is SNRNP35.

Small Nuclear Ribonucleoprotein U1 Subunit 70

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 (PubMed:19325628, PubMed:25555158).
SNRNP70 binds to the loop I region of U1-snRNA (PubMed:2467746, PubMed:19325628, PubMed:25555158).
Isoform 3
Truncated isoforms that lack the RRM domain cannot bind U1-snRNA.
Isoform 4
Truncated isoforms that lack the RRM domain cannot bind U1-snRNA.
