FUS Protein, Human (MBP-His)

FUS Protein, Human (MBP-His) is the recombinant human-derived FUS protein, expressed by E. coli, with N-His & N-MBP tag.

TLS/FUS is a DNA/RNA-binding protein involved in multiple cellular processes including transcription regulation, RNA splicing, RNA transport, DNA repair, and damage response. It specifically binds single-stranded RNA containing the 5'-AGGUAA-3' consensus sequence and interacts with nascent pre-mRNAs, serving as a molecular bridge between RNA polymerase II and U1 small nuclear ribonucleoprotein to couple transcription with splicing. The protein autoregulates its expression by binding its own pre-mRNA via nonsense-mediated decay. During DNA double-strand break repair, it promotes D-loop formation and homologous recombination. In neuronal cells (by similar), it plays essential roles in dendritic spine formation/stability, RNA transport, mRNA stability, and synaptic homeostasis.

Approximately 95 kDa, based on SDS-PAGE under reducing conditions, due to the glycosylation.

Greater than 85% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from 0.22 μm filtered solution of PBS, pH7.4 with trehalose as protectant.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
