It typically weighs around 44 kDa. This protein contains a high-mobility group (HMG) box domain that enables it to bind specifically to DNA and influence gene expression. LEF1 is primarily expressed in tissues with active Wnt signaling including developing organs and certain cell types like T-cells specifically Jurkat cells. Researchers use LEF1 protein immunohistochemistry (LEF1 IHC) and LEF1 markers for expression analysis in different tissues.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe LEF1 transcription factor plays a significant role in cellular processes such as cell differentiation proliferation and embryonic development. As part of the Wnt signaling complex it interacts with β-catenin to regulate target gene expression. Activation of Wnt signaling by LEF1 can lead to changes in the cellular structure and function necessary for tissue development and regeneration. LEF1 also contributes to maintaining the pluripotency of stem cells by modulating gene networks critical for stem cell properties.\u003cbr\u003e\nPathways\u003cbr\u003e\nThe LEF1 protein is essential in Wnt\/β-catenin signaling and influences the Hedgehog pathway. LEF1 pairs with β-catenin to drive the transcription of Wnt target genes involved in cell cycle and differentiation. These pathways maintain stem cell populations and regulate development. LEF1's function in these pathways links it closely to other factors like TCF7L2 and GLI family proteins which also play vital roles within these signaling cascades.\u003cbr\u003e\nLEF1 can be linked to conditions such as cancer and immune-related diseases. Overexpression or mutation of the LEF1 protein can lead to various types of cancers including leukemia and colorectal cancer by promoting abnormal cell proliferation and survival. LEF1's role in the immune system also associates it with autoimmune diseases where dysregulation of Wnt signaling might contribute to disease progression. Altered interactions between LEF1 and β-catenin or other associated proteins can disrupt normal cellular activities leading to these pathologies.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843576221865,"sku":"ab289647","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab289647","provider":"Iright","version":"1.0","type":"link"}
