  • 関連性p35 is a neuron-specific activator of cyclin-dependent kinase 5 (CDK5); the activation of CDK5 is required for proper development of the central nervous system. The p35 form of this protein is proteolytically cleaved by calpain, generating a p25 form. P25 deregulates CDK5 activity by prolonging its activation and changing its cellular location. The p25 form accumulates in the brain neurons of patients with Alzheimer's disease. This accumulation correlates with an increase in CDK5 kinase activity, and may lead to aberrantly phosphorylated forms of the microtubule-associated protein tau, which contributes to Alzheimer's disease.

Application Western blot
Review text: The blot image provided in this review has mouse Dorsal Striatum loaded at 70ug in lanes 2-7 and the P35/P25-GST lysate in .5, 1 and 3 ug in lanes 8-10. The .5ug amount appears to be the least necessary to produce both the p35-GST and p25-GST bands. The p25-GST band is much stronger than the p35-GST band. A goat polyclonal anti-GST antibody was used from GE Health sciences. Therefore, lanes 8-10 have a yellow band because of co-labeling of p35/p25 and the GST tag. There was some nonspecific binding with the p35/p25-GST lysate due to such a high amount being used. These bands are found mainly below the p25 band. There was also nonspecific binding with the anti-GST antibody within the p35/p25-GST lysate but not the Dorsal Striatum lysates. Only p35 appears in the Dorsal Striatum lanes because the 10% gel was not able to resolve p25 because it is too light. 12.5% gels have been used to resolve both p35 and p25 in previous studies, but this percent gel would not have been able to resolve the GST tagged proteins. A gradient gel would be necessary.
