Downstream of kinase 3 (DOK3) is a 53kD (predicted) member of the DOK family of cytoplasmic adaptor proteins and is expressed in B cells and macrophages. It contains one pleckstrin homology region (aa63-179) and an IRS-type phosphotyrosine binding domain (PTB) (aa213-317). Alternate splicing generates additional isoforms with extensive N-terminal and C-terminal truncations and substitutions. Phosphorylation of tyrosine residues in DOK3 regulates its interaction with SH2 and SH3 containing proteins, leading to inhibition of signaling from immunoreceptors. Over (aa181-271), human DOK3 shares approximately 80% aa sequence identity with mouse and rat DOK3.
