  Function in Host
Component of the spliceosomal U1 snRNP, which is essentialfor recognition of the pre-mRNA 5' splice-site and the subsequentassembly of the spliceosome. U1 snRNP is the first snRNP to interactwith pre-mRNA. This interaction is required for the subsequent bindingof U2 snRNP and the U4/U6/U5 tri-snRNP. SNRPA binds stem loop II of U1snRNA. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNAsplicing and polyadenylation process. May bind preferentially to the5'-UGCAC-3' motif on RNAs. [1]
