Protein attributes
| Sequence length | 3102 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Promotes the exchange of GDP by GTP. Together with leukocyte antigen-related (LAR) protein, it could play a role in coordinating cell-matrix and cytoskeletal rearrangements necessary for cell migration and cell growth By similarity. |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Subunit structure | Interacts to form a complex with leukocyte antigen related protein By similarity. |
| Subcellular location | Cytoplasm. Note: Isoform 2 localizes to early endosomes. Ref.1 |
| Tissue specificity | Widespread in the brain, with more intense signals in the hippocampus, olfactory bulb, cortical layers and cerebellum. Isoform 2 is predominantly expressed in Purkinje neurons of brain. Ref.1 |
| Domain | The N-terminal DBL/GEF domain specifically catalyzes nucleotide exchange for RAC1, leading to the activation of Jun kinase and the production of membrane ruffles. The second DBL/GEF domain is an exchange factor for rhoa and induces the formation of stress fibers By similarity. |
| Sequence similarities | Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. Contains 1 CRAL-TRIO domain. Contains 2 DH (DBL-homology) domains. Contains 1 Ig-like C2-type (immunoglobulin-like) domain. Contains 2 PH domains. Contains 1 protein kinase domain. Contains 1 SH3 domain. Contains 6 spectrin repeats. |
| Sequence caution | The sequence BAE32258.1 differs from that shown. Reason: Erroneous initiation. |
