Recombinant Human GINS3 Protein

Product Name: Recombinant Human GINS3 Protein
Catalog #:  HRP-2841
Manufacture:  LD Biopharma, Inc.
Intruduction:

Human DNA replication complex GINS protein PSF3 (GINS3) gene encodes a member of GINS complex, which plays an essential role in the initiation of DNA replication, and progression of DNA replication forks. GINS complex seems to bind preferentially to single-stranded DNA. As a component of the GINS complex which is a hetero-tetramer of GINS1, GINS2, GINS3 and GINS4. It forms a stable sub-complex with GINS2. GINS complex interacts with DNA primase in vitro.

Full-length human GINS3 cDNA (215aa, Isoform-I) was constructed with codon optimization gene synthesis and expressed with a human N-terminalT7-His-TEV cleavage site Tag (29aa) fusion. This protein was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.

Applications:
  1. May be used for in vitro IMPDH2 mediated IMP/XMP metabolic signaling pathway regulation for cancer cell study using intracellular delivery of recombinant human IMPDH2 protein with protein delivery reagent such as ProFectin.
  2. May be used for IMPDH2 protein-protein interaction assay.
  3. May be used as specific substrate protein for IMPDH2 specific kinase, and ubiquitin (Sumo pathway) related enzyme functional screening assays.
  4. Potential therapeutic protein, which may be used for anti-neuroinflammation therapy drug development.
  5. As native human IMPDH2 immunogen for specific antibody production.
