Abstract
The present invention relates to the discovery in eukaryotic cells, particularly mammalian cells, of a family of cell-cycle regulatory proteins (“CCR-proteins”). As described herein, this family of proteins includes a polypeptide having an apparent molecular weight of 16 kDa, and a polypeptide having an apparent molecular weight of approximately 15 kDa, each of which can function as an inhibitor of cell-cycle progression, and therefore ultimately of cell growth. The present invention comprises antibodies directed to such CCR-proteins.
Claims4
An isolated antibody specifically immunoreactive with a 16 kD protein that co-precipitates with CDK4 from cell lysates of SV40-transformed WI38 cells in the presence of an anti-CDK4 antibody, wherein the molecular weight of the 16 kD protein is identified by polyacrylamide gel electrophoresis (PAGE) under denaturing conditions.
An isolated antibody specifically immunoreactive with a p16 protein comprising SEQ ID NO:
- 35.
