Brat is a Drosophila protein involved in mRNA metabolism. Mutation of its gene results in the irregularly sized and shaped cells of tumours.
One side of this fly head has been damaged by tumorous growth. A dramatic view of how crippling this diseased growth can be to healthy tissue.
Brat is a protein in Drosophila that plays a role in mRNA metabolism, mutation of this protein results in tumour growth. Tumours are the result of uncontrolled cell growth. This can either be the result of cells dividing too many times and producing larger populations of cells that usual, or it can be caused by cells developing into a larger size than usual.
