General description

Drebrin is a member of the newly identified ADF-H family of actin-binding proteins that share the structurally conserved actin-depolymerizing factor (ADF) binding module. It is composed of a single ADF-H domain at its N-terminus, followed by a non-conserved central region and a C-terminal SH3 domain. Three isoforms, E1 and E2 (embryonic) and A (adult), have been identified in the brain. An additional truncated form of drebrin A, s-drebrin/A2, is specifically expressed in the adult brain, but not in non-neuronal tissues. Drebrin is also widely expressed in a variety of cells including epithelial, endothelial, and smooth muscle cells and is associated at cell-cell adhering junction sites.

Immunogen

synthetic peptide corresponding to the N-terminal region of human drebrin E/A (amino acids 22-42) conjugated to KLH.

Biochem/physiol Actions

Drebrin (developmentally-regulated brain protein) is a major neuronal F-actin binding protein involved in the control of actin dynamics and neuronal morphogenesis. It colocalizes with actin filaments and dendritic-like cell processes and may be involved in actin remodeling. It binds to and dissociates F-actin stabilizing proteins such as α-actinin, fascin, and tropomyosin from actin filaments. It plays an important role in the formation of axons and dendrites during neuronal development and in neuronal plasticity in the adult brain.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Drebrin is a development-associated neuroprotein whose cDNA into fibroblasts causes the formation of dendrite-like structures (Shirao, T., Kojima, N., and Obata, K. (1992) Neuroreport 3, 109-112). To explore molecular functions of drebrin during brain development, we purified drebrin from brains
