Rabbit USP2 Polyclonal Antibody | anti-USP2 antibody

RABBIT ANTI HUMAN USP2

Cat. Num. AAA221443

• Gene Names: USP2; USP9; UBP41
• Applications: Immunohistochemistry
• Synonyms: USP2; Polyclonal Antibody; RABBIT ANTI HUMAN USP2; anti-USP2 antibody

• Host: Rabbit
• Clonality: Polyclonal
• Isotype: IgG
• Specificity: This item detects an epitope within the internal region of human ubiquitin specific protease 2 (USP2), also known as UBP41. USP2 is a deubiquitinating protease which rescues proteins from the ubiquitin mediated 26S proteasomal pathway. The USP2 gene encodes two splice variants- USP2a and USP2b, with molecular weights of 69kD and 48kD respectively. ; ; USP2a deubiquitinates the antiapoptotic proteins fatty acid synthase (FAS) and Mdm2. FAS is overexpressed in the majority of epithelial tumours, including prostate cancer, whilst Mdm2 indicates that USP2 may regulate p53-dependent pathways.

NCBI Description

This gene encodes a member of the family of de-ubiquitinating enzymes, which belongs to the peptidase C19 superfamily. The encoded protein is a ubiquitin-specific protease which is required for TNF-alpha (tumor necrosis factor alpha) -induced NF-kB (nuclear factor kB) signaling. This protein deubiquitinates polyubiquitinated target proteins such as fatty acid synthase, murine double minute 2 (MDM2), MDM4/MDMX and cyclin D1. MDM2 and MDM4 are negative regulators of the p53 tumor suppressor and cyclin D1 is required for cell cycle G1/S transition. Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Aug 2011]

Uniprot Description

USP2: Hydrolase that deubiquitinates polyubiquitinated target proteins such as MDM2, MDM4 and CCND1. Isoform 1 and isoform 4 possess both ubiquitin-specific peptidase and isopeptidase activities. Deubiquitinates MDM2 without reversing MDM2-mediated p53/TP53 ubiquitination and thus indirectly promotes p53/TP53 degradation and limits p53 activity. Has no deubiquitinase activity against p53/TP53. Prevents MDM2-mediated degradation of MDM4. Plays a role in the G1/S cell-cycle progression in normal and cancer cells. Plays a role in the regulation of myogenic differentiation of embryonic muscle cells. Homooligomer. Found in trimeric complex with MDM2 and MDM4 and UPB2. Interacts with CCND1; the interaction is direct and promotes its stabilization by antagonizing ubiquitin-dependent degradation. Interacts (via N-terminus and C- terminus) with MDM2. Interacts with MDM4. Down-regulated by cisplatin. Expressed in mesangial cells of the kidney and in different types of glomerulonephritides. Cleavage is inhibited by ubiquitin in a dosage- dependent manner. Cleavage is blocked by ubiquitin aldehyde. Belongs to the peptidase C19 family. USP2 subfamily. 4 isoforms of the human protein are produced by alternative splicing.
