SNURF Like Protein (SNURFL)

SNURFL Belongs to the SNURF family. SNURF is one polypeptide of a small nuclear ribonucleoprotein complex and belongs to the snRNP SMB/SMN family. The protein plays a role in pre-mRNA processing, possibly tissue-specific alternative splicing events. Although individual snRNPs are believed to recognize specific nucleic acid sequences through RNA-RNA base pairing, the specific role of this family member is unknown. The protein arises from a bicistronic transcript that also encodes a protein identified as the SNRPN upstream reading frame (SNURF). Multiple transcription initiation sites have been identified and extensive alternative splicing occurs in the 5""" untranslated region. Additional splice variants have been described but sequences for the complete transcripts have not been determined. The 5""" UTR of this gene has been identified as an imprinting center.
