HNRNPU encodes heterogeneous nuclear ribonucleoprotein U (hnRNP U), a chromatin-associated RNA-binding protein that couples transcription with pre-mRNA processing and coordinates higher-order genome organization. hnRNP U participates in RNA polymerase II–dependent gene expression, alternative splicing, and RNA localization, and contributes to nuclear architecture through interactions with scaffold/matrix attachment regions and long noncoding RNAs. Through these functions, it influences pathways governing cell-cycle progression, DNA damage responses, and lineage-specific transcriptional programs. Dysregulation or loss of hnRNP U activity has been associated with neurodevelopmental phenotypes and altered gene expression networks relevant to neurological disease and cancer biology.
hnRNP U Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HNRNPU locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HNRNPU. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt HNRNPU function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of HNRNPU-disrupted clones.
