The transcription factor TFCP2L1 induces expression of distinct target genes and promotes self-renewal of mouse and human embryonic stem cells.

ABSTRACT: TFCP2L1 (transcription factor CP2-like 1) is a transcriptional regulator critical for maintaining mouse and human embryonic stem cell (ESC) pluripotency. However, the direct TFCP2L1 target genes are uncharacterized. Here, using gene overexpression, immunoblotting, quantitative real-time PCR, ChIP, and reporter gene assays, we show that TFCP2L1 primarily induces estrogen-related receptor β (Esrrb) expression that supports mouse ESC identity and also selectively enhances Kruppel-like factor 4 (Klf4) expression and thereby promotes human ESC self-renewal. Specifically, we found that in mouse ESCs, TFCP2L1 binds directly to the Esrrb gene promoter and regulates its transcription. Esrrb knockdown impaired Tfcp2l1's ability to induce interleukin 6 family cytokine (leukemia inhibitory factor)-ind
