Scientific Background: ACK1 (TNK2) is a protein-tyrosine kinase of the TK group and Ack family. It appears to be a tumour suppressor protein (TSP). Cancer-related mutations in ACK1 in human tumours point to a loss of function of the protein kinase. The active form of the protein kinase normally acts to inhibit tumour cell proliferation. It is implicated in numerous roles, including: cell spreading and migration, cell survival, cell growth, and proliferation. TNK2 is known to phosphorylate: Akt1, AR, MCF2, WASL and WWOX. In this capacity TNK2 negatively regulates the tumour suppressor, WWOX, whilst activating the oncoproteins, Akt1 and AR. Mutations in this gene have been observed in ovarian, skin, and stomach tumours. Phosphorylation at Y284 in ACK1 increases its phosphotransferase activity. Its SH3 domain appears to play an autoinhibitory role.
