Scientists define key binding characteristics of protein associated with heart disease and breast cancer

Scientists define key binding characteristics of protein associated with heart disease and breast cancer

Galectins attach to other proteins via the carbohydrates on their surfaces (sugar-binding proteins). As such they impact on a range of processes in the cell associated with a number of diseases, including heart disease and breast cancer – the most common cancer in women worldwide, with 1.7 million new cases diagnosed in 2012 alone.
