TGFB-induced factor homeobox 2 (TGIF2)

TGFB-induced factor homeobox 2 (TGIF2) is a DNA-binding homeodomain transcriptional repressor, belonging to the atypical TALE (Three Amino acid Loop Extension) homeodomain family[3][2]. TGIF2 regulates transcription by binding DNA directly or by interacting with TGF-beta-activated SMAD proteins, and represses gene expression through the recruitment of histone deacetylases[1][3][5]. It is critical for embryonic development, especially in neural patterning, and modulates TGF-beta/Nodal and Sonic Hedgehog (SHH) signaling pathways[2]. Aberrant TGIF2 expression is implicated in the progression of cancers such as ovarian, lung, gastric, hepatocellular carcinoma, cervical, glioma, and skin cancer, often correlating with enhanced proliferation, invasion, metastasis, and poor prognosis[1]. In addition, mutations in TGIF2 can cause holoprosencephaly and congenital nervous system disorders[3][4]. Currently, TGIF2 is considered a potential therapeutic target due to its oncogenic roles[1][3].
