UCHL3, Ubiquitin thioesterase L3

Source

Human UCH-L3 / UCHL3 Protein (Human UCH-L3, His Tag) Glu 2 - Ala 230 (Accession # AAH18125) was produced in E.coli cells at ACROBiosystems.

Molecular Characterization

Human UCH-L3, His Tag is fused with a polyhistidine tag at the N-terminus, and has a calculated MW of 27 kDa. The predicted N-terminus is Met. The reducing (R) protein migrates as 27 kDa in SDS-PAGE .

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM tris, 150 mM NaCl, pH7.5. Normally Trehalose are added as protectants before lyophilization.

Background

Ubiquitin carboxyl-terminal hydrolase isozyme L3 (UCH-L3), a member of peptidase C12 family, is also known as ubiquitin thioesterase L3. Deubiquitinating enzyme (DUB) that controls levels of cellular ubiquitin through processing of ubiquitin precursors and ubiquitinated proteins. UCH-L3 is a thiol protease that recognizes and hydrolyzes a peptide bond at the C-terminal glycine of either ubiquitin or NEDD8. UCH-L3 indirectly increases the phosphorylation of IGFIR, AKT and FOXO1 and promotes insulin-signaling and insulin-induced adipogenesis. It is also required for stress-response retinal, skeletal muscle and germ cell maintenance. Furthermore, UCH-L3 may be involved in working memory and can hydrolyze UBB(+1), a mutated form of ubiquitin which is not effectively degraded by the proteasome and is associated with neurogenerative disorders.
