SNRPA / U1A

small nuclear ribonucleoprotein polypeptide A

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. U1 snRNP 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. SNRPA binds stem loop II of U1 snRNA. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process. May bind preferentially to the 5'-UGCAC-3' motif on RNAs.

Gene Name: small nuclear ribonucleoprotein polypeptide A
Synonyms: SNRPA, U1A, Mud1, U1 snRNP A, U1 snRNP-specific protein A, U1-A
Target Sequences: NM_004596 NP_004587.1 P09012

SNRPA / U1A Antibody - Immunohistochemical analysis of SNRPA staining in mouse brain formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with hematoxylin and mounted with DPX.
