The first number describes the quality of cleavage (on a scale of 1-3 1=perfect; 2=good; 3=poor), and the second number describes the number of directions that exhibit cleavage. For example, a gemstone with a cleavage of 1,2 has perfect cleavage in 2 directions.
WebCyclin-dependent kinase 5 (Cdk5) hyperactivity is an important driver of pathology in neurodegeneration. Normally, Cdk5 is regulated by association with its co-activators p35 or p39. Cdk5 hyperactivity is caused by calpain-mediated cleavage of p35 into the truncated activator p25, which binds to Cdk5 and leads to prolonged activation and ...
