General annotation (Comments)
| Function | Downstream effector of CDC42 which mediates CDC42-dependent cell migration via phosphorylation of BCAR1. Binds to both poly- and mono-ubiquitin and regulates ligand-induced degradation of EGFR. Participates in clathrin-mediated endocytosis. May be involved both in adult synaptic function and plasticity and in brain development. Ref.8 |
| Catalytic activity | ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. |
| Cofactor | Magnesium. |
| Enzyme regulation | The SH3 domain appears to play an autoinhibitory role. |
| Subunit structure | Interacts with CDC42. Interacts with activated CSPG4 By similarity. |
| Subcellular location | |
| Tissue specificity | Ubiquitously present in all tisssues tested. Highly expressed in the hippocampus, neocortex, and cerebellum, both at dendritic spines and presynaptic axon terminals. Levels are strongly up-regulated by increased neural activity. Ref.1 Ref.5 |
| Developmental stage | Highly expressed at E14-E16 in the forebrain, in the proliferative ventricular zone of the neocortex and hippocampus, and in the cortical and hippocampal plates. Also observed in the septal area, the ganglionic eminence, and in the dorsal thalamus and hypothalamus. In the hindbrain, expressed in many nuclei in the brain stem and in the cerebellar anlage, external granule cell layer, in Purkinje cells and the deep cerebellar nuclei. Ref.5 |
| Sequence similarities | Belongs to the protein kinase superfamily. Tyr protein kinase family. Contains 1 CRIB domain. Contains 1 protein kinase domain. Contains 1 SH3 domain. |
| Sequence caution | The sequence AAH31168.1 differs from that shown. Reason: Miscellaneous discrepancy. Contaminating sequence. Sequence of unknown origin in the N-terminal part. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: O54967-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 2 (identifier: O54967-2) The sequence of this isoform differs from the canonical sequence as follows: 515-531: REPPPRPPQPAIFTQKT → KP 980-1011: Missing. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 3 (identifier: O54967-3) The sequence of this isoform differs from the canonical sequence as follows: 515-531: REPPPRPPQPAIFTQKT → KP |
