Detection of Human HOMER1 by Western Blot. Western blot shows lysates of human brain (cerebellum) tissue and IMR‑32 human neuroblastoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-HOMER1 Monoclonal Antibody (Catalog # MAB6889) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for HOMER1 at approximately 52 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 5.
Detection of Human and Mouse HOMER1 by Simple WesternTM. Simple Western lane view shows lysates of human brain (cerebellum) tissue, loaded at 0.2 mg/mL. A specific band was detected for HOMER1 at approximately 51 kDa (as indicated) using 20 µg/mL of Mouse Anti-Human/Mouse/Rat HOMER1 Monoclonal Antibody (Catalog # MAB6889). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

HOMER1 is an approximately 48 kDa cytoplasmic protein that regulates the cell surface localization of neuronal mGluR1 and mGluR5 metabotropic glutamate receptors. It also functions in striated muscle mechanotransduction and excitation-contraction coupling by regulating the localization of transient receptor potential (TRP) channels and the coupling of ryanodine receptors to Cav1.2 calcium channels. Alternately spliced isoforms of human HOMER1 lack either the C-terminal half of the molecule (aa 178-354) or 130 aa following the WH1 domain (aa 99-228). Particular isoforms show distinct effects on hippocampal neuronal plasticity and the maintenance of extracellular glutamate levels in the prefrontal cortex. Within aa 73-82, human HOMER1 shares 100% aa sequence identity with mouse and rat HOMER1.
