HTF-1539 Recombinant Human TCEA1 Protein $300

Recombinant Human TCEA1 Protein

Product Name: Recombinant Human TCEA1 Protein
Catalog #:  HTF-1539
Manufacture:  LD Biopharma, Inc.

Human transcription elongation factor A protein 1 (TCEA1) is necessary for efficient RNA polymerase II transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by S-II allows the resumption of elongation from the new 3'-terminus. As recent data indicated that RNA polymerase II elongation rate controls a sub-population gene mRNA splicing, TCEA1 may plays a role in regulating mRNA splicing too.

Full-length human TCEA1 cDNA (300aa) was constructed with codon optimization technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. It was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
