Dok-3 Polyclonal Antibody

Domain:PTB domain mediates receptor interaction., function:DOK proteins are enzymatically inert adaptor or scaffolding proteins. They provide a docking platform for the assembly of multimolecular signaling complexes. DOK3 is a negative regulator of JNK signaling in B-cells through interaction with INPP5D/SHIP1. May modulate ABL function., PTM:Constitutively tyrosine-phosphorylated., PTM:On IL2 stimulation, phosphorylated on C-terminal tyrosine residues possibly by Src kinases. Can also be phosphorylated by ABL kinase., similarity:Belongs to the DOK family. Type A subfamily., similarity:Contains 1 IRS-type PTB domain., similarity:Contains 1 PH domain., subunit:On tyrosine phosphorylation, interacts with CSK and INPP5D/SHIP1 via their SH2 domains. Both Tyr-381 and Tyr-398 are required for interaction with INPP5D. Only Tyr-381 is required for interaction with CSK. Binds ABL through the PTB domain and in a kinase-dependent manner. Does not interact with RasGAP., tissue specificity:Expressed in spleen.
