Chemical Properties
| Description | The ubiquitin speci c protease 3 USP3 is a deubiquitinating enzyme for uH2A and uH2B. |
| In vitro | USP3 has been characterized as a functional DUB in vitro, and it is the human DUB most homologous to S. cerevisiae Ubp8, which regulates H2B deubiquitination2-4. |
| In vivo | USP3 dynamically associates with chromatin and deubiquitinates H2A/H2B in vivo. The ZnF-UBP domain of USP3 mediates uH2AUSP3 interaction. Functional ablation of USP3 by RNAi leads to delay of S phase progression and to the accumulation of DNA breaks, with ensuing activation of DNA damage checkpoint pathways. In response to ionizing radiation, (1) uH2A redistributes and colocalizes in g-H2AX DNA repair foci, and (2) USP3 is required for full deubiquitination of ubiquitin-conjugates/uH2A and g-H2AX dephosphorylation. USP3 is a novel regulator of H2A and H2B ubiquitination, highlight its role in preventing replication stress and suggest its involvement in the response to DNA double-strand breaks1. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
