Small nuclear ribonucleoprotein-associated protein N

SNRPN (small nuclear ribonucleoprotein-associated protein N) is a 240-amino acid protein encoded by the SNRPN gene (UniProt: P63162). The protein may be involved in tissue-specific alternative RNA processing events, suggesting a role in post-transcriptional gene regulation through interaction with small nuclear ribonucleoproteins.

SNRPN is part of the snRNP complex machinery, which functions broadly in pre-mRNA splicing and other RNA-processing pathways. The protein's specific tissue-dependent functions remain incompletely characterized in the available data.

SNRPN is classified as a syndromic autism-associated gene by SFARI (SFARI Cat S), indicating evidence for association with autism spectrum disorder, particularly in syndromic presentations. This classification reflects its potential relevance to neurodevelopmental disorders, though specific molecular mechanisms linking SNRPN dysfunction to autism phenotypes require further investigation.
