描述:
Docking proteins interact with receptor tyrosine kinases and mediate particular biological responses. DOK3 is a negative regulator of JNK signaling in B-cells through interaction with INPP5D/SHIP. May modulate Abl function. On tyrosine phosphorylation, interacts with CSK and INPP5D/SHIP 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. 4 isoforms of the human protein are produced by alternative splicing.

研究背景

功能:

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 ABL1 function (By similarity).

翻译修饰:

Constitutively tyrosine-phosphorylated.

On IL2 stimulation, phosphorylated on C-terminal tyrosine residues possibly by Src kinases. Can also be phosphorylated by ABL1 kinase (By similarity).
