Description: P62dok (downstream of tyrosine kinases) was identified as a target of protein tyrosine kinases. Following phosphorylation, p62[dok] binds to Ras GTPase activatin protein (RasGap), indicating a role for p62[dok] in intracellular signaling pathways. p62[dok] contains several motifs that signify its important interactions with signaling proteins. These domains include the pleckstrin homology (PH) domain in the amino terminus, numerous tyrosines in the C-terminus, and ten PXXP motifs. p56[dok2] (Dok-R, FRIP) is 35% identical to p62[dok], and contains a PH domain, a central Dok homology motif (DKH), multiple tyrosine phosphorylation sites, and six PXXP motifs. Similar to p62[dok], p56[dok2] binds p120 RasGap, and may act as an adaptor molecule between RasGap and receptor complexes. p56[dok2] is expressed in tissues of hematopoietic origin, and is phosphorylated by the cytokines, IL-2, IL-3, and IL-4. In addition, p56[dok2] may act as an adaptor signaling molecule for the endothelial-specific receptor tyrosine kinase (RTK), Tek/Tie2. Thus, p56[dok2] is a second member of the Dok RasGap-binding family of proteins, which act as adaptor molecules in RTK signaling.

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
