Background: DOK3

DOK3 (downstream of kinase 3) is a 53 kDa (predicted) member of the DOK family of cytoplasmic adaptor proteins and is expressed in B cells and macrophages. Human DOK3 cDNA encodes 496 amino acids (aa) including one pleckstrin homology region (aa 63‑179) and an IRS-type phosphotyrosine binding domain (PTB) (aa 213‑317). Alternate splicing generates 330, 228 and 216 aa isoforms with N-terminal and C-terminal truncations and substitutions. Human DOK3 shares approximately 80% aa sequence identity with mouse and rat DOK3 within aa 181‑271, which are common to all four isoforms. Phosphorylation of tyrosine residues in DOK3 regulates its interaction with SH2 and SH3 containing proteins, leading to inhibition of signaling from immunoreceptors.
