Popis

General description

Recombinant, mouse PKA catalytic subunit expressed in E. coli. Regulates a number of cellular functions including gene expression, carbohydrate metabolism, Ca²⁺ homeostasis, and ion channel function. Suitable for studying the phosphorylation of purified substrates and for use with cell extracts. Unlike the holoenzyme, the catalytic subunit does not require cAMP for activation.

Recombinant, mouse PKA catalytic subunit expressed in E. coli. The catalytic subunit of protein kinase A that combines with the regulatory subunit, in the absence of cAMP, to form the inactive PKA holoenzyme. Unlike the holoenzyme, the catalytic subunit does not require cAMP for activation. PKA-Cα is reported to potentiate IP₃-induced Ca²⁺ mobilization in isolated hepatocytes. Suitable for studies of PKA phosphorylation in vitro with purified substrates or following the introduction into intact cells or cell extracts.
