Belonging to the FBXO31 family, F-box only protein 31 (FBXO31) is a component of the SCF (SKP1-cullin-F-box) ubiquitin ligase complex and is involved in cyclin binding. At the protein level, FBXO31 plays a central role in G1 arrest following DNA damage. More specifically, these F-box proteins interact with SKP1 and recognize phosphorylated cyclin-D1 (CCND1), promoting its ubiquitination and degradation by the proteasome, thus resulting in G1 arrest. Diseases associated with FBXO31 include breast cancer, mast cell neoplasm, esophagitis and carcinoma.

Concentration Calculator

The concentration calculator allows you to quickly calculate the volume, mass or concentration of your vial. Simply enter your mass, volume, or concentration values for your reagent and the calculator will determine the rest.


Molarity Calculator

Calculate the mass, volume, or concentration required for a solution.

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
