The protein encoded by this gene is a neuron-specific activator of CDK5 kinase. It associates with CDK5 to form an active kinase. This protein and neuron-specific CDK5 activator CDK5R1/p39NCK5A both share limited similarity to cyclins, and thus may define a distinct family of cyclin-dependent kinase activating proteins Common labeling conventions The NPK analysis label. Fertilizers are usually labeled with three numbers, as in 18-20-10, indicating the relative content of the macronutrients nitrogen (N), phosphorus (P), and potassium (K), respectively.. More precisely, the first number (N value) is the percentage of elemental nitrogen by weight in the fertilizer; that is, the mass fraction of nitrogen times. When producers pay special attention to managing phosphorus (P), it can lead to profitable crop production. The best way to use fertilizers to meet P requirements changes with crop, soil properties and environmental conditions. Finding the best P source Inorganic commercial P fertilizers have evolved over the last several decades into a refined, predictable product. Plus, there are the organic.
