A18192B_PURE_HOMER1_Antibody_WB_020723
Whole cell extracts (15 µg total protein) from the indicated cell lines were resolved on a 4-12% Bis-Tris gel, transferred to a PVDF membrane, and probed with 0.5 µg/mL of purified anti-HOMER1 (clone A18192B) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse IgG (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:50000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426318) was used as a detection agent. Lane M: Molecular weight marker

Description

HOMER1 is a scaffolding protein that is a major component of the post-synaptic density (PSD), a region in the plasma membrane of the post-synaptic neuron that interacts with the pre-synaptic active zone of upstream neurons. HOMER1 consists of two domains, a C-terminal coiled-coil domain that is required for HOMER1 dimerization, and an EVH1 domain involved in protein-protein interaction. Dimerized long-form HOMER1 (variants designated as Homer1b and Homer1c) is constitutively expressed in neurons, where it plays a role in neurotransmitter receptor signaling and trafficking by cross-linking associated proteins via the EVH1 domain. Truncated HOMER1 (Homer1a) is expressed as a result of neuronal activity, and lacking the coiled-coil domain, is incapable of dimerizing and cannot crosslink interacting proteins. Thus, Homer1a acts as a dominant-negative regulator of HOMER1 and is thought to provide negative feedback against excessive neuronal activity.
