Data Example

Western Blot Detection of Human C4.4A/LYPD3 by Western Blot. View Larger

Detection of Human C4.4A/LYPD3 by Western Blot. Western blot shows lysates of HT-29 human colon adenocarcinoma cell line cancer tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human C4.4A/LYPD3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5428) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for C4.4A/LYPD3 at approximately 75 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: C4.4A/LYPD3

LYPD3 (Ly6/PLAUR-domain containing protein 3; also MIG-C4 and GPI anchored metastasis-associated protein C4.4A) is an 85‑95 kDa, variably glycosylated member of the Ly6 family of GPI anchored proteins. It is expressed on transitional epithelium, keratinocytes and monocytes, and binds laminin 1 and 5, plus Galectin‑3. LYPD3 is believed to support cell migration. Mature human LYPD3 is a 296 amino acid (aa) GPI linked glycoprotein. It contains two UPAR domains
(aa 33‑126 and 140‑222), and an ADAM cleavage site (aa 312‑325). The molecule shows extensive N and O linked glycosylation. There is one potential isoform that shows a deletion of aa 129‑180. Over aa 31‑286, human LYPD3 shares 81% aa identity with mouse LYPD3.
