Function

Transcription factor that binds to the immunoglobulin enhancer Mu-E5/KE5-motif. Involved in the initiation of neuronal differentiation. Activates transcription by binding to the E box (5'-CANNTG-3'). Binds to the E-box present in the somatostatin receptor 2 initiator element (SSTR2-INR) to activate transcription (By similarity). Preferentially binds to either 5'-ACANNTGT-3' or 5'-CCANNTGG-3'.

Activity summary

The transcription factor 4 (TCF-4) also known as TCF7L2 is an important regulator of transcriptional activity. This protein weighs approximately 68 kDa and is widely expressed in multiple tissues including the pancreas intestine and brain. Through its function as a transcription factor TCF-4 binds to specific DNA sequences influencing the expression of target genes. The regulation it provides is essential for various biological processes especially during developmental stages.

Biological function summary

TCF-4 plays an important role in Wnt signaling a pathway critical for cell growth and differentiation. It partners with β-catenin to form a functional complex enabling it to activate gene expression. This interaction influences cellular processes such as cell cycle regulation fate determination and maintenance of stem cell populations. As such TCF-4 serves an important role in regulating a balance between proliferation and differentiation in developing tissues.

Pathways

TCF-4 is an important component within the canonical Wnt/β-catenin signaling pathway. This pathway is pivotal in embryogenesis and is also involved in the control of cell communication processes. TCF-4 interacts with other pathway members such as the APC protein which are essential for stabilizing β-catenin enabling successful transcriptional regulation. Its activity connects it chemically to the TCF/LEF family of proteins which all participate actively in gene transcription related to Wnt signaling.

Associated diseases and disorders

TCF-4 has been implicated in type 2 diabetes and certain forms of cancer. Research shows that mutations in the TCF7L2 gene alter its function leading to increased susceptibility to type 2 diabetes emphasizing its role in glucose metabolism. Moreover dysregulation of the Wnt signaling pathway in which TCF-4 is an actor has been associated with cancer pathogenesis including colorectal cancer. TCF-4 connects closely with β-catenin and APC in these conditions highlighting its involvement in tumorigenic processes when its regulation fails.

    Cal-1 cells (Human plasmacytoid dendritic cell line) were cross-linked with 1% formaldehyde for 5 min at RT. Cross-linked cells were first washed with ice-cold PBS and then resuspended in ice-cold RIPA buffer (10mM Tris-HCl pH8, 140 mM NaCl, 1mM EDTA pH 8, 0.5 mM EGTA, 1% Triton X-100, 0.1% SDS and 0.1% Sodium Deoxycholate) to a final concentration of 5x106 cells/ml. DNA was sheared with a Misonix XL sonicator, by performing 12 x 45'' sonication cycles at power setting of 5. For each ChIP reaction, 2x107 chromatin cell equivalents were incubated overnight with10 μg of Anti-TCF-4 antibody [NCI-R159-6] ab217668.
