Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

Drebrin A Antibody recognizes endogenous levels of total Drebrin A protein. This antibody does not cross-react with Drebrin E.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala330 of mouse Drebrin A protein. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using Drebrin A Antibody.

IP

IP

Immunoprecipitation of Drebrin A from SH-SY5Y cell extracts, using Normal Rabbit IgG #2729 (lane 2) or Drebrin A Antibody (lane 3). Lane 1 is 10% input. Western blot analysis was performed using Drebrin A Antibody.

Background

Developmentally-regulated brain proteins (Drebrins) are cytoplasmic proteins that were originally identified in the brain as F-actin-binding proteins. There are two mammalian isoforms: adult type (A) and embryonic type (E). These isoforms are derived from a single gene through alternative RNA splicing mechanisms (1). Drebrin E has been observed to accumulate in the developmental stage of migrating neurons and in the growing cell processes of neurons. Drebrin A is found at the dendritic spines of mature cortical neurons where it plays a role in synaptic plasticity (2,3). Although drebrins are primarily found in neurons, they have also been found in skeletal muscle, heart, pancreas, and kidney. Research studies have shown that reduced expression of drebrin in the brain could be associated with Alzheimer’s Disease, Down Syndrome (4), and bipolar disorders (5).
