Tcf

TCF is an acronym that can refer to several distinct concepts across finance, education, and biology. This article outlines some of the more widely encountered uses.

In finance, TCF Financial Corporation was a United States financial services company based in Minnesota that operated as TCF Bank. In 2021, it was acquired by Huntington Bancshares Incorporated, and the combined company adopted the Huntington Bank brand, with former TCF branches rebranded accordingly. The firm had a regional footprint and offered consumer and commercial banking products and services before the merger.

In language testing, TCF stands for Test de connaissance du français, a standardized French-language proficiency test administered by France Education International (formerly CIEP). It evaluates listening, reading, writing, and, in some formats, speaking. Variants exist for specific purposes, such as TCF DAP for admission to French higher education and TCF ANF for proof of French language ability related to nationality or residence. Results are issued as certificates with defined validity periods and are used for study, immigration, employment, and professional licensing, depending on the requirements of the requesting institution.

In biology, TCF refers to the T cell factor family of transcription factors (also part of the broader TCF/LEF family) involved in gene regulation within the Wnt signaling pathway. TCF proteins interact with beta-catenin to regulate target genes, influencing development, stem cell biology, and disease processes. Several human TCF genes exist, including TCF7, TCF7L1, TCF7L2, and TCF7L3, each with distinct roles in cellular function and organismal development.
