Transcription elongation factor A protein-like 7 (TCEAL7)

Plays a role in the negative regulation of NF-kappa-B signaling at the intermediate level by modulating transcriptional activity of NF-kappa-B on its target gene promoters. Associates with cyclin D1 promoter containing Myc E-box sequence and transcriptionally represses cyclin D1 expression.

Regulates telomerase reverse transcriptase expression and telomerase activity in both ALT (alternative lengthening of telomeres)and telomerase-positive cell lines. .
