Product Description Rabbit Polyclonal antibody recognizes DOK1 / p62 Dok phospho (Tyr362)
Tested Reactivity Hu, Ms, Rat
Tested Application ELISA, WB
Specificity This antibody was cross-adsorbed to a phosphotyrosine peptide before affinity purification using phospho-Dok1 (Tyr-362) peptide. The purified antibody detects a band at ~62 kDa corresponding to Dok1 in western blots of human Jurkat cells, but does not detect this band after alkaline phosphatase treatment. Similar to Dok1 (Ser-450) antibody, this antibody also detects an 80 kDa band that has not been identified.
Host Rabbit
Clonality Polyclonal
Target Name DOK1 / p62 Dok
Antigen Species Human
Immunogen KLH-conjugated phosphospecific peptide around Tyr362 in human Dok1 protein. This sequence is conserved in Dok1 from rat and mouse (Tyr361), and has high homology to Dok2 (Tyr337). The site is not conserved in other Dok family members.
Conjugation Un-conjugated
Alternate Names dok; p62; P62DOK; Docking protein 1; pp62; Downstream of tyrosine kinase 1

Background Doks are a family of adaptor proteins that include six Dok proteins (Dok1 to Dok6), which have an N-terminal pleckstrin homology domain, a central phosphotyrosine binding domain, and a C-terminal region containing multiple tyrosine residues. When phosphorylated, these tyrosines can serve as docking sites for SH2 domain-containing proteins. Dok1 (p62dok) has been shown to bind Ras-GAP, Nck, and Csk. Several tyrosine phosphorylation sites have been identified for Dok1. One site, Tyr-362 (Tyr-361 mouse), is phosphorylated by c-Abl, is required for Nck binding, and may be critical for filopodia formation during fibroblast spreading on fibronectin. Alternatively, Dok1 activity is also regulated by serine phosphorylation. IκB Kinase β phosphorylates several serine sites including Ser-450 in vitro, and TNFα, IL-1, and radiation treatment lead to phosphorylation of Ser-443, Ser-446, and Ser-450 in vivo. Phosphorylation of these serine sites may be required for Dok-mediated inhibition of MAPK signaling and stimulation of cell motility.
Function DOK proteins are enzymatically inert adaptor or scaffolding proteins. They provide a docking platform for the assembly of multimolecular signaling complexes. DOK1 appears to be a negative regulator of the insulin signaling pathway. Modulates integrin activation by competing with talin for the same binding site on ITGB3. [UniProt]
