Human Ubiquitin Carboxyl-Terminal Hydrolase 8 (USP8) ELISA Kit | USP8 elisa kit
Human Ubiquitin Carboxyl-Terminal Hydrolase 8 (USP8) ELISA Kit
* Allow all reagents to warm to room temperature for at least 30 minutes before opening.
* Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
* Unused wells must be kept desiccated at 4 degree C in the sealed bag provided.
* Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
* It is recommended that all samples and standards be assayed in duplicate or triplicate.
Background: Ubiquitin, a highly conserved protein involved in the regulation of intracellular protein breakdown, cell cycle regulation, and stress response, is released from degraded proteins by disassembly of the polyubiquitin chains. During analysis of randomly sampled human coding sequences from the myeloid cell line KG-1, Nomura et al. (1994) identified a novel cDNA, which they referred to as KIAA0055, that was related to the tre2 oncogene. Janssen et al. (1998) found that HUMORF8 encodes a putative deubiquitinating enzyme. Janssen et al. (1998) analyzed DNA from a patient with chronic myeloproliferative disorder. They identified an oncogenic fusion of the 5-prime end of p85-beta with the 3-prime end of HUMORF8.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a protein that belongs to the ubiquitin-specific processing protease family of proteins. The encoded protein is thought to regulate the morphology of the endosome by ubiquitination of proteins on this organelle and is involved in cargo sorting and membrane trafficking at the early endosome stage. This protein is required for the cell to enter the S phase of the cell cycle and also functions as a positive regulator in the Hedgehog signaling pathway in development. Pseudogenes of this gene are present on chromosomes 2 and 6. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
Uniprot Description
Hydrolase that can remove conjugated ubiquitin from proteins and therefore plays an important regulatory role at the level of protein turnover by preventing degradation. Converts both 'Lys-48' an 'Lys-63'-linked ubiquitin chains. Catalytic activity is enhanced in the M phase. Involved in cell proliferation. Required to enter into S phase in response to serum stimulation. May regulate T-cell anergy mediated by RNF128 via the formation of a complex containing RNF128 and OTUB1. Probably regulates the stability of STAM2 and RASGRF1. Regulates endosomal ubiquitin dynamics, cargo sorting, membrane traffic at early endosomes, and maintenance of ESCRT-0 stability. The level of protein ubiquitination on endosomes is essential for maintaining the morphology of the organelle. Deubiquitinates EPS15 and controles tyrosine kinase stability. Removes conjugated ubiquitin from EGFR thus regulating EGFR degradation and downstream MAPK signaling. Involved in acrosome biogenesis through interaction with the spermatid ESCRT-0 complex and microtubules. Deubiquitinates BIRC6/bruce and KIF23/MKLP1.

Product Notes
The Human USP8 usp8 (Catalog #AAA9713747) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA9713747 ELISA Kit recognizes Human USP8. It is sometimes possible for the material contained within the vial of "Ubiquitin Carboxyl-Terminal Hydrolase 8 (USP8), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
