Descriptions

The p21-activated kinases (PAKs) controls cytoskeletal actin assembly and activate MAP-kinase pathways. In a study with PAK1 (Q13153), the kinase domain in the C terminus of PAK1 is inhibited by the IS domain via the C lobe, in which the kinase inhibitory segment hinders a part of the kinase domain and stabilizes a disabled catalytic site.

1 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

6 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
MAP kinase kinase activity Catalysis of the concomitant phosphorylation of threonine (T) and tyrosine (Y) residues in a Thr-Glu-Tyr (TEY) thiolester sequence in a MAP kinase (MAPK) substrate.
metal ion binding Binding to a metal ion.
protein serine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate.
protein serine/threonine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.
SH3 domain binding Binding to a SH3 domain (Src homology 3) of a protein, small protein modules containing approximately 50 amino acid residues found in a great variety of intracellular or membrane-associated proteins.

9 GO annotations of biological process

Name Definition
axonogenesis De novo generation of a long process of a neuron, including the terminal branched region. Refers to the morphogenesis or creation of shape or form of the developing axon, which carries efferent (outgoing) action potentials from the cell body towards target cells.
dendrite development The process whose specific outcome is the progression of the dendrite over time, from its formation to the mature structure.
dendritic spine morphogenesis The process in which the anatomical structures of a dendritic spine are generated and organized. A dendritic spine is a protrusion from a dendrite and a specialized subcellular compartment involved in synaptic transmission.
intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
protein phosphorylation The process of introducing a phosphate group on to a protein.
regulation of actin cytoskeleton organization Any process that modulates the frequency, rate or extent of the formation, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins.
regulation of actin filament polymerization Any process that modulates the frequency, rate or extent of the assembly of actin filaments by the addition of actin monomers to a filament.
regulation of axonogenesis Any process that modulates the frequency, rate or extent of axonogenesis, the generation of an axon, the long process of a neuron.
regulation of MAPK cascade Any process that modulates the frequency, rate or extent of signal transduction mediated by the MAP kinase (MAPK) cascade.
