Related Product Information for anti-USP4 antibody
Ubiquitinating enzymes (UBEs) catalyze protein ubiquitination, a reversible process countered by deubiquitinating enzyme (DUB) action (1, 2). Five DUB subfamilies are recognized, including the USP, UCH, OTU, MJD, and JAMM enzymes. USP4 was originally identified during a survey of murine genes near the Mpv20 retroviral insertion site and intially referred to as Ubiquitous Nuclear Protein (UNP). Analysis of the mouse cDNA originally identified Usp4/Unp as a proto-oncogene related to the human tre-2/tre-17/USP6 proto-oncogene (3, 4). Usp4/Unp was subsequently observed to contain the conserved Cys and His boxes of the UBP family (5, 6) as well as DUB activity (7, 8). In a study of primary lung tumor tissue, it was observed that the human homolog of Usp4, USP4/UNPH, had elevated gene expression levels in small cell tumors and adenocarcinomas of the lung, suggesting a causative role for USP4 in neoplasia (6). Another recent study demonstrated overexpression of USP4 in several types of human cancer and that USP4 positively contributes to cell transformation by negatively regulating p53 levels (9). Both murine and human USP4 have been shown to interact with the Rb family of tumor suppressor proteins, providing additional mechanistic evidence of a role for USP4 in cellular transformation (10, 11).

NCBI Description

The protein encoded by this gene is a protease that deubiquitinates target proteins such as ADORA2A and TRIM21. The encoded protein shuttles between the nucleus and cytoplasm and is involved in maintaining operational fidelity in the endoplasmic reticulum. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

Uniprot Description

USP4: Hydrolase that deubiquitinates target proteins such as the receptor ADORA2A, PDPK1 and TRIM21. Deubiquitination of ADORA2A increases the amount of functional receptor at the cell surface. Plays a role in the regulation of quality control in the ER. Interacts with RB1 (both dephosphorylated and hypophosphorylated forms). Interacts with ADORA2A (via cytoplasmic C-terminus); the interaction is direct. Interacts with RB1, RBL1 and RBL2. Overexpressed in small cell tumors and adenocarcinomas of the lung compared to wild-type lung. Expressed in the hippocampal neurons. Belongs to the peptidase C19 family. USP4 subfamily. 2 isoforms of the human protein are produced by alternative splicing.

Protein type: Ubiquitin-specific protease; Protease; EC 3.4.19.12; Oncoprotein; Ubiquitin conjugating system

Chromosomal Location of Human Ortholog: 3p21.3

Cellular Component: lysosome; cytoplasm; plasma membrane; nucleus

Molecular Function: identical protein binding; protein binding; cysteine-type endopeptidase activity; metal ion binding; ubiquitin-specific protease activity; adenosine receptor binding

Biological Process: assembly of spliceosomal tri-snRNP; proteasomal ubiquitin-dependent protein catabolic process; protein deubiquitination; regulation of protein stability; negative regulation of protein ubiquitination

Product Notes

The USP4 usp4 (Catalog #AAA3009498) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The USP4 Polyclonal Antibody reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's USP4 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemistry (IHC). WB: 1:500-1:2000 IHC: 1:50-1:200. Researchers should empirically determine the suitability of the USP4 usp4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "USP4, Polyclonal Antibody" 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.
