Introduction
SPRY Domain-Containing SOCS Cox Protein 2 (SPSB2) belongs to a suppressor of cytokine signaling (SOCS) family, and is a member of the subfamily of proteins containing a central SPRY (repeats in splA and RyR) domain and a C-terminal SOCS box. SPSB2 is present in a gene-rich cluster on chromosome 12p13 in the vicinity of the CD4 antigen and triosephosphate isomerase genes. SPSB2 is apparent substrate recognition component of a SCF-like ECS (Elongin BC-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase complex that mediates the ubiquitination and ensuing proteasomal degradation of target proteins.
Description
SPSB2 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 287 amino acids (1-263 a.a) and having a molecular mass of 31.2kDa.
SPSB2 is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
