Detection of Human DGK‑δ by Western Blot. Western blot shows lysates of TT human medullary thyroid cancer cell line and K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human DGK‑δ Monoclonal Antibody (Catalog # MAB7426) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for DGK‑δ at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Diacylglycerol kinase delta (DGK-δ) is a widely expressed 140 kDa member of the DGK family of kinases that phosphorylate the lipid diacylglycerol. DGK-δ contains a pleckstrin homology domain (aa 53-146), two zinc finger domains (aa 163-213 and aa 235-286), a catalytic domain (aa 317-451), and a sterile alpha motif (aa 1145‑1208). An isoform of DGK-δ with a shortened N-terminus is expressed predominantly in ovary and spleen. The two isoforms can form intracellular homooligomers or heterooligomers with each other. The oligomers are disrupted by PKC following phorbol ester stimulation. DGK-δ regulates PKC mediated signaling downstream of the EGF receptor. Within aa 570-717, human DGK-δ shares 82% aa sequence identity with mouse and rat DGK-δ.
