title: [The temperature dependence of protein kinase A and C activity in variant mouse neuroblastoma cells differing genetically in their heat resistance].
abstract: The ability of the mouse neuroblastoma cell line NTR to proliferate at 40 degrees C correlates with the position of the temperature optimum of protein kinases A and C activities in the region of higher temperatures compared to those for cells of the original line N18AI, and with higher thermostability of protein kinase A after its heating at various elevated temperatures. The found changes in protein kinases A and C in the cells of NTR line mean that the selection of variants, capable of growing at elevated temperatures, is accompanied with conformational protein changes.
