ID:DOK2_HUMAN DESCRIPTION: RecName: Full=Docking protein 2; AltName: Full=Downstream of tyrosine kinase 2; AltName: Full=p56(dok-2); FUNCTION: DOK proteins are enzymatically inert adaptor or scaffolding proteins. They provide a docking platform for the assembly of multimolecular signaling complexes. DOK2 may modulate the cellular proliferation induced by IL-4, as well as IL-2 and IL-3. May be involved in modulating Bcr-Abl signaling. Attenuates EGF-stimulated MAP kinase activation (By similarity). SUBUNIT: Interacts with phosphorylated RASGAP and EGFR. Interacts with RET and NCK. Interacts (via PH domain) with TEK/TIE2 (tyrosine phosphorylated) (By similarity). TISSUE SPECIFICITY: Highly expressed in peripheral blood leukocytes, lymph nodes and spleen. Lower expression in thymus, bone marrow and fetal liver. DOMAIN: PTB domain mediates receptor interaction. PTM: On immunoreceptor stimulation, phosphorylated on C-terminal tyrosine residues. Phosphorylation on Tyr-345 is required for binding to the SH2 domain of NCK. Phosphorylation on both Tyr-271 and Tyr-299 is required for interaction with RASGAP. Phosphorylated on tyrosine residues by TEK/TIE2 (By similarity). SIMILARITY: Belongs to the DOK family. Type A subfamily. SIMILARITY: Contains 1 IRS-type PTB domain. SIMILARITY: Contains 1 PH domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
