Descriptions

CRK regulates transcription and cytoskeletal reorganization for cell growth and motility by linking tyrosine kinases to small G proteins. The SH2 and nSH3 domains are used to recruit their target proteins. In CRKII, the intramolecular interactions of the SH domains with the inter-domain linker between nSH3 and cSH3 (inter-SH3 region) result in a compact structure.The binding site of SH2 in CRKII is exposed, but nSH3 is masked by SH2. In addition, cSH3 acts as a stabilizer of the assembled structure and thus as a negative regulator of CRKII function. Mutations disrupting the core structure of CRKII disturb the assembly of the SH domains, allowing nSH3 to effectively bind target proteins and transmit signals, thus promoting cell growth and motility.

6 GO annotations of cellular component

Name Definition
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
extrinsic component of postsynaptic membrane The component of the postsynaptic membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region.
neuromuscular junction The junction between the axon of a motor neuron and a muscle fiber. In response to the arrival of action potentials, the presynaptic button releases molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane of the muscle fiber, leading to a change in post-synaptic potential.
nucleoplasm That part of the nuclear content other than the chromosomes or the nucleolus.
protein-containing complex A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
synapse The junction between an axon of one neuron and a dendrite of another neuron, a muscle fiber or a glial cell. As the axon approaches the synapse it enlarges into a specialized structure, the presynaptic terminal bouton, which contains mitochondria and synaptic vesicles. At the tip of the terminal bouton is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic terminal bouton secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
