HNRNPU belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). Additionally we are shipping Heterogeneous Nuclear Ribonucleoprotein U (Scaffold Attachment Factor A) Antibodies (65) and Heterogeneous Nuclear Ribonucleoprotein U (Scaffold Attachment Factor A) Proteins (5) and many more products for this protein.

We found that heterogeneous nuclear ribonucleoprotein U (hnRNP U) is essential for the expression of Avp (show AVP ELISA Kits) and Vip (show Vip ELISA Kits). Loss of one copy of the Hnrnpu gene resulted in fragmented locomotor activities and disrupted metabolic rhythms. Hnrnpu(+/-) mice were more active than wild-type mice in the daytime but more inactive at night.
findings provide conclusive evidence for the essential role of hnRNP U in heart development and function and in the regulation of alternative splicing.
SAF-A interacts with BRG1 and both components are required for RNA Polymerase II Mediated Transcription
Macrophage expression of hnRNP U was induced by TLR stimulation. hnRNP U knockdown attenuated & overexpression increased TLR-induced expression of TNF-alpha (show TNF ELISA Kits), IL-6 (show IL6 ELISA Kits) & IL-1beta (show IL1B ELISA Kits). hnRNP U bound to the mRNA of these cytokines via the RGG motif.
Data report that endogenous SAF-A is involved in regulation of Oct4 (show POU5F1 ELISA Kits) expression, binds the Oct4 (show POU5F1 ELISA Kits) proximal promoter in ES cells, and dissociates from the promoter upon early differentiation induced by LIF (show LIF ELISA Kits) withdrawal.
hnRNP-U engages a highly neddylated active SCF (show KITLG ELISA Kits) beta-TrCP (show BTRC ELISA Kits) which dissociates in the presence of a high-affinity substrate, resulting in the ubiquitination of the latter.
hnRNP U participates in nuclear regulatory events that are involved in mammalian central and peripheral circadian clocks.
nuclear matrix protein SAF-A binds to the 3'-flanking region of the Bmal1 (show ARNTL ELISA Kits) gene with circadian timing
HnRNP U binding to the 5'-UTR (show UTS2R ELISA Kits) of the Shh (show SHH ELISA Kits) facilitates gene expression during limb development.
SAF-A was found to be localized in three different domains: outside the chromosomes, on the surface of the chromosome arms, and in the centromere region where it apparently binds specifically to the satellite DNA.
This series demonstrates common phenotypic features, including emerging dysmorphism, associated with heterozygous HNRNPU mutations. This allows us to define a novel neurodevelopmental syndrome, with a likely mechanism of haploinsufficiency
SAF-A, in concert with Ku, temporally regulates base damage repair in irradiated cell genome.
HNRPU deletion is associated with neurodevelopmental disorders.
We broaden the clinical and mutational HNRNPU-associated spectrum, and demonstrate that heterozygous HNRNPU variants cause epilepsy, severe intellectual disability with striking speech impairment and variable central nervous system, cardiac, and renal anomalies.
Results show that SAF-A and caRNAs form a dynamic, transcriptionally responsive chromatin mesh that organizes large-scale chromosome structures and protects the genome from instability.
results confirm and refine the complex genotype-phenotype correlations existing in the 1qter microdeletion syndrome and define more precisely the neurodevelopmental phenotypes associated with genetic alterations of AKT3 (show AKT3 ELISA Kits), ZBTB18 and HNRNPU in humans
mutual regulatory mechanisms exist between PP4 (show ANXA5 ELISA Kits) and SAF-A. Interactions between PP4 (show ANXA5 ELISA Kits) and SAF-A played a role in prometaphase/metaphase transition.
CENP-W (show CENPW ELISA Kits) interacts with hnRNPU and may contribute to kinetochore-microtubule attachment in mitotic cells.
Nuclear TDP-43 becomes neurotoxic by escaping from the inhibitory regulation by hnRNP-U or hnRNP-A2. hnRNP-U inhibits TDP-43-mediated alterations in splicing of POLDIP3 mRNA.
These results suggest that HNRNPU, FAM36A, and NCRNA00201 are not major genes for microcephaly and corpus callosum abnormalities but are good candidates for intellectual disability (ID) and seizures.
This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA binding proteins and they form complexes with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene contains a RNA binding domain and scaffold-associated region (SAR)-specific bipartite DNA-binding domain. This protein is also thought to be involved in the packaging of hnRNA into large ribonucleoprotein complexes. During apoptosis, this protein is cleaved in a caspase-dependent way. Cleavage occurs at the SALD site, resulting in a loss of DNA-binding activity and a concomitant detachment of this protein from nuclear structural sites. But this cleavage does not affect the function of the encoded protein in RNA metabolism. At least two alternatively spliced transcript variants have been identified for this gene.
