Kinase domain polypeptide of human protein kinase B gamma (AKT3)
View Patent ↗The present invention provides, in part, AKT3 polypeptides and methods of use thereof along with nucleic acids encoding the polypeptides. For example, methods for screening for AKT3 inhibitors are provided herein.
1. An isolated polypeptide consisting of an amino acid sequence selected from the group consisting of the amino acid sequence of SEQ ID NO: 1, the amino acid sequence of amino acids 24-347 of SEQ ID NO: 1, and the amino acid sequence of amino acids 28-347 of SEQ ID NO: 1.
2. A crystal of a polypeptide consisting of the amino acid sequence of amino acids 28-347 of SEQ ID NO: 1, the crystal having space group P2 1 2 1 2 1 and unit cell dimensions selected from the group consisting of:
1) a=48.679 Å, b=73.357 Å, and c=95.468 Å,
2) a=49.093 Å, b=73.528 Å, and c=95.559 Å, and
3) a=49.015 Å, b=73.365 Å, and c=95.375 Å.
3. A composition comprising the isolated polypeptide of claim 1 complexed with a polypeptide comprising an amino acid sequence selected from the group consisting of the amino acid sequence of SEQ ID NO: 6 and the amino acid sequence of SEQ ID NO: 14.
4. An aqueous solution comprising the isolated polypeptide of claim 1 and a buffer.
5. An aqueous solution comprising the composition of claim 3 and a buffer.
