Mouse anti Human hnRNP U antibody recognizes the heterogeneous nuclear ribonucleoprotein U, also known as p120 nuclear protein, scaffold attachment factor A and SAFA.

The heterogeneous nuclear ribonucleoproteins (hnRNPs) are a ubiquitously-expressed family of RNA-binding proteins that contribute to alternative splicing, mRNA stabilization, and regulation of transcription and translation. hnRNP U is the largest member of the hnRNP family, and is predominantly found in the nucleus where it binds to pre-mRNA and single-stranded DNA and is involved with transcription and alternative splicing (Geuens et al. 2016). hnRNP U is required for cell viability, with a hypomorphic mutation causing early embryonic lethality in mice (Roshon and Ruley 2005). Epigenetic inactivation of one of the two female X chromosomes, equalizing gene expression with male mammals, also depends on hnRNP U activity (Hasegawa et al. 2010).
