ENOSF1 (Enolase Superfamily Member 1): ENOSF1 is a protein involved in the cellular response to vitamin B2 (riboflavin) availability. It plays a role in the metabolism of cancer cells, especially in how they adapt to changes in nutrient conditions. Changes in ENOSF1 expression have been studied in relation to tumor metabolism, indicating a possible role in cancer progression and the development of targeted therapies that exploit metabolic weaknesses in cancer cells.
