Recombinant Human Transcriptio

Transcription elongation factor A (SII)-like 7, TCEA-like protein 7, transcription elongation factor A protein-like 7, MGC23947, MPMGp800C04260Q003.

Transcription Elongation Factor A (SII)-Like 7 (TCEAL7) has a role in the negative regulation of NF-kappa-B signaling at the basal level by controlling transcriptional activity of NF-kappa-B on its target gene promoters. TCEAL7 links with cyclin D1 promoter containing Myc E-box sequence and transcriptionally inhibits cyclin D1 expression. TCEAL7 regulates telomerase reverse transcriptase expression and telomerase activity in both alternative lengthening of telomeres (ALT) and telomerase-positive cell lines. TCEAL7 is highly expressed in normal and fetal brain tissues, and weakly expressed in the uterus and ovary. TCEAL7 is down-regulated in epithelial ovarian, cervical, prostate, breast, brain and lung cancer cell lines and in the brain and ovarian tumors.

TCEAL7 Human Recombinant produced in E. coli is a single polypeptide chain containing 124 amino acids (1-100) and having a molecular mass of 14.8 kDa.
TCEAL7 is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

E.coli.

Sterile Filtered colorless solution.

The TCEAL7 solution (0.5mg/1ml) contains 20mM Tris-HCl buffer (pH 8.0), 200mM NaCl, 2mM DTT and 50% glycerol.
