Scientific Data Images for Human Drebrin 1 Antibody (838102)

Detection of Human Drebrin 1 antibody by Western Blot.

Detection of Human Drebrin 1 by Western Blot.

Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and Jurkat human acute T cell leukemia cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Drebrin 1 Monoclonal Antibody (Catalog # MAB7739) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Drebrin 1 at approximately 120 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Drebrin 1 antibody in HeLa Human Cell Line by Immunocytochemistry (ICC).

Drebrin 1 in HeLa Human Cell Line.

Drebrin 1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human Drebrin 1 Monoclonal Antibody (Catalog # MAB7739) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the Northern-Lights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell membrane and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Detection of Human Drebrin 1 by Simple WesternTM.

Simple Western lane view shows lysates of Jurkat human acute T cell leukemia cell line, loaded at 0.5 mg/mL. A specific band was detected for Drebrin 1 at approximately 162 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human Drebrin 1 Monoclonal Antibody (Catalog # MAB7739). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Drebrin 1

Drebrin 1 (DBN-1 [developmentally-regulated brain protein1]; also drebrin-E/E2 [Embryonic]) is an intracellular member of the ADF-H (actin-depolymerizing factor-H) family of actin binding proteins. Although its predicted MW is 72 kDa, it runs anomalously at 115-116 kDa in SDS-PAGE. It is expressed by neurons, gastric Parietal cells, astrocytes, distal convoluted tubule epithelium and proton-secreting intercalated cells of the renal collecting duct. Drebrin 1 interacts with multiple partners near the membrane. It links connexin-43 and F-actin, thereby stabilizing membrane gap junctions. It also binds to EB3 (end-binding protein 3) on microtubules, facilitating actin-microtubule interactions. Human Drebrin 1 is 649 amino acids (aa) in length. It contains one actin depolymerizing homology domain (aa 3-134), an actin-binding region (≈ aa 150-300), and two HOMER binding motifs (aa 539-543 and 617-621). There are at least 10 utilized Ser/Thr phosphorylation sites and one utilized Tyr phosphorylation site. Alternative splicing generates drebrin-A (Adult), a 124-126 kDa isoform that contains a 46 aa insert after Gly319. Drebrin-A is found in neurons and possibly podocytes, and is associated with dendritic spines where it inhibits the interaction of F-actin with alpha -actinin and tropomyosin. This favors the generation of excitatory impulses in neurons. Three other potential isoform variants are noted. One utilizes an alternative start site at Met64, a second shows a 60 aa substitution for aa 1-110, and a third contains a 28 aa substitution for aa 4-29. Over aa 482-649, human Drebrin 1 shares 84% aa sequence identity with mouse Drebrin 1.
