USP3 Antibody (N-term)

Purified Rabbit Polyclonal Antibody (Pab)

     
  • WB - USP3 Antibody (N-term) AP2132a
    Western blot analysis of anti-USP3 Antibody (N-term) (Cat.#AP2132a) in 293 cell line lysates (35ug/lane). USP3 (arrow) was detected using the purified Pab.

Protein Information
Name USP3
Function Hydrolase that deubiquitinates monoubiquitinated target proteins such as histone H2A and H2B. Required for proper progression through S phase and subsequent mitotic entry. May regulate the DNA damage response (DDR) checkpoint through deubiquitination of H2A at DNA damage sites. Associates with the chromatin.
Cellular Location Nucleus. Note=Localizes preferentially with monoubiquitinated H2A to chromatin
Tissue Location Expressed in all tissues examined, with strongest expression in pancreas

Background

Modification of target proteins by ubiquitin participates in a wide array of biological functions. Proteins destined for degradation or processing via the 26 S proteasome are coupled to multiple copies of ubiquitin. However, attachment of ubiquitin or ubiquitin-related molecules may also result in changes in subcellular distribution or modification of protein activity. An additional level of ubiquitin regulation, deubiquitination, is catalyzed by proteases called deubiquitinating enzymes, which fall into four distinct families. Ubiquitin C-terminal hydrolases, ubiquitin-specific processing proteases (USPs),1 OTU-domain ubiquitin-aldehyde-binding proteins, and Jab1/Pad1/MPN-domain-containing metallo-enzymes. Among these four families, USPs represent the most widespread and represented deubiquitinating enzymes across evolution. USPs tend to release ubiquitin from a conjugated protein. They display similar catalytic domains containing conserved Cys and His boxes but divergent N-terminal and occasionally C-terminal extensions, which are thought to function in substrate recognition, subcellular localization, and protein-protein interactions.
