Abstract
The present invention relates to a novel tumor suppressor gene, SSeCKS. The SSeCKS gene product is a substrate of protien kinase C and acts as a mitogenic regulator and as an inhibitor of the transformed phenotype. In various embodiments, the present invention relates to the SSeCKS gene and protein and in particular, to rat and human SSeCKS gene and protein. Furthermore, the present invention provides for the use of such genes and proteins in diagnostic and therapeutic methods.
Claims9
A purified and isolated nucleic acid molecule comprising the nucleic acid sequence set forth in FIG. 11 (SEQ ID NO:3).
A purified and isolated protein comprising the amino acid sequence as set forth in FIG. 11 (SEQ ID NO:4).
A purified and isolated DNA which hybridizes to the nucleic acid molecule of SEQ ID NO:3 under the following stringent hybridization conditions:
- 0.75 M sodium phosphate pH 7, 1 mM EDTA, 7% SDS, 1% bovine serum albumin (BSA), 100 micrograms per ml salmon sperm DNA at 12-18 hours at 65 degrees C.;
- washing twice in 50 mM sodium phosphate, 1 mM EDTA, 1% SDS and 0.5% BSA at 65 degrees C. and twice again in the same solution without BSA at 65 degrees C.;
- and wherein said nucleic acid molecule codes for a protein:
- (i) that is a protein kinase C substrate;
- (ii) that is resistant to heat denaturation wherein said resistance can be measured by the ability of the protein to remain soluble after boiling for five minutes in the absence of SDS;
- (iii) that is myristylated;
- and
- (iv) growth inhibitory.
