[[3bo2]] is a 5 chain structure of [[Kink-turn motif]], [[Nucleoprotein]], [[Ribozyme]] and [[User:Wayne Decatur/kink-turn motif]] with sequence from [http://en.wikipedia.org/wiki/Homo_sapiens Homo sapiens].

== Function ==
 +
[https://www.uniprot.org/uniprot/SNRPA_HUMAN SNRPA_HUMAN] Binds stem loop II of U1 snRNA. It is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process. Binds preferentially to the 5'-UGCAC-3' motif in vitro.<ref>PMID:9848648</ref>
