Dok-1 Rabbit Polyclonal Antibody

Docking protein 1 (DOK1) Homo sapiens The protein encoded by this gene is part of a signal transduction pathway downstream of receptor tyrosine kinases. The encoded protein is a scaffold protein that helps form a platform for the assembly of multiprotein signaling complexes. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2016], domain:The 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. 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., PTM:Constitutively tyrosine-phosphorylated., PTM:Phosphorylated on tyrosine residues by the insulin receptor kinase. Results in the negative regulation of the insulin signaling pathway., similarity:Belongs to the DOK family. Type A subfamily., similarity:Contains 1 IRS-type PTB domain., similarity:Contains 1 PH domain., subunit:Interacts with ABL (By similarity) . Interacts with RasGAP and INPP5D/SHIP1. Interacts directly with phosphorylated ITGB3., tissue specificity:Expressed in pancreas, heart, leukocyte and spleen. Expressed in both resting and activated peripheral blood T-cells.
