| 摘要 |
The present invention relates to an isolated full-length Chp polypeptide, a biologically-active polypeptide fragment thereof, and nucleic acids which code for it. This polypeptide has various activities in regulating cell signalling and signal transduction pathways, including, e.g. a PAK regulatory domain binding activity, a PAK kinase stimulatory activity, a JNK kinase stimulatory activity, a cytoskeletal-reorganizing activity, or a Chp-specific immunogenic activity. The invention relates to all aspects of Chp, or homologs thereof, including assays for modulators, activators, ligands, etc.
