Expression Expression Expression Expression Host: E.coli

Function: Function: Function: Function: Hydrolase that can remove conjugated ubiquitin from proteins in vitro and

may therefore play an important regulatory role at the level of protein turnover by

preventing degradation. Regulator of T-cell anergy, a phenomenon that occurs when

T-cells are rendered unresponsive to antigen rechallenge and no longer respond to their

cognate antigen. Acts via its interaction with RNF128/GRAIL. Surprisingly, it regulates

RNF128-mediated ubiquitination, but does not deubiquitinate polyubiquitinated RNF128.

Deubiquitinates estrogen receptor alpha (ESR1). Mediates deubiquitination of

'Lys-48'-linked polyubiquitin chains, but not 'Lys-63'-linked polyubiquitin chains. Not able

to cleave di-ubiquitin. Also capable of removing NEDD8 from NEDD8 conjugates, but

with a nuch lower preference compared to 'Lys-48'-linked ubiquitin.

[ BACKGROUND BACKGROUND BACKGROUND BACKGROUND]

The target protein is fused with a His-tag and its sequence is listed below. The first Met is an initiator amino acid. Moreover, Gly and Ser are added to improve the flexibility of N-terminus at both ends of the His-tag, which will

increase the chelating ability of the tag to Ni-Sepharose during purification.
