DOK proteins are enzymatically inert adaptor or scaffolding proteins. They provide a docking platform for the assembly of multimolecular signaling complexes. DOK6 promotes Ret-mediated neurite growth. May have a role in brain development and/or maintenance (By similarity). Interacts via its PTB domain with phosphorylated RET. PTB domain mediates receptor interaction. On Ret activation, phosphorylated on one or more C-terminal tyrosine residues by an Src family kinase. Belongs to the DOK family. Type B subfamily.
