| Summary: | Polycystin-1 is a putative 460 kDa membrane protein with a unique structure and is possibly representative of a new family of proteins. Its structure suggests an involvement in cell signalling and cell-matrix interactions. The amino acid sequence of polycystin-1 has to date been predicted from its gene sequence. This, to our knowledge, is the first report of the isolation and analysis of polycystin-1 at the protein level using mass spectrometry to confirm its predicted structure. The availability of purified polycystin-1 will allow a new approach to unravelling the complexity of the cell-cell and cell-matrix interactions of this large molecule in normal cells and its perturbation in disease. |
