Descriptions

PKA is a major intracellular receptor of cAMP and modulates diverse cellular signalings. The N-terminal regulatory domain contains a pseudosubstrate sequence that may interact with the catalytic kinase domain.

6 GO annotations of cellular component

Name Definition
axoneme The bundle of microtubules and associated proteins that forms the core of cilia (also called flagella) in eukaryotic cells and is responsible for their movements.
cAMP-dependent protein kinase complex An enzyme complex, composed of regulatory and catalytic subunits, that catalyzes protein phosphorylation. Inactive forms of the enzyme have two regulatory chains and two catalytic chains; activation by cAMP produces two active catalytic monomers and a regulatory dimer.
centrosome A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
nucleotide-activated protein kinase complex A protein complex that possesses nucleotide-dependent protein kinase activity. The nucleotide can be AMP (in S. pombe and human) or ADP (in S. cerevisiae).
plasma membrane raft A membrane raft that is part of the plasma membrane.

5 GO annotations of molecular function

Name Definition
cAMP binding Binding to cAMP, the nucleotide cyclic AMP (adenosine 3',5'-cyclophosphate).
cAMP-dependent protein kinase inhibitor activity Binds to and stops, prevents or reduces the activity of a cAMP-dependent protein kinase.
protein domain specific binding Binding to a specific domain of a protein.
protein kinase A catalytic subunit binding Binding to one or both of the catalytic subunits of protein kinase A.
ubiquitin protein ligase binding Binding to a ubiquitin protein ligase enzyme, any of the E3 proteins.

1 GO annotations of biological process

Name Definition
negative regulation of cAMP-dependent protein kinase activity Any process that stops, prevents or reduces the frequency, rate or extent of cAMP-dependent protein kinase activity.
