Description; General description; Homer proteins are cytoplasmic adaptor proteins that contain the Ena/VASP homology 1 domain that binds to the PPXXF sequence motifs found in Ca2+ handling proteins such as IP3 receptors, transient receptor potential canonical (TRPC) channels and ryanodine receptor (RyR) Ca2+ release channels. HOMER1, a calcium signaling complex modulator, is involved in the opening and closing of TRPC channels such as the endoplasmic reticulum store-operated Ca2+ -influx channels (SOCs). Homer1 plays a critical role in determining the apoptotic susceptibility to TRAIL, an apoptotic cell death-inducing ligand that belongs to a TNF superfamily.; Specificity; Anti-HOMER1 (AB2) polclonal antibody reacts with canine, human, mouse, rat, and bovine homer 1 adaptor proteins.; Immunogen; Synthetic peptide directed towards the N terminal region of human HOMER1; Application; Anti-HOMER1 (AB2) polclonal antibody is used to tag the homer 1 for detection and quantitation by Western blotting and in plasma by immunohistochemical (IHC) techniques. It is used as a probe to determine the roles of homer 1 as a modulator of calcium transport and signaling involved in apoptosis, body movement and various cellular processes.; Physical form; Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.; Disclaimer; Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.; Biochem/physiol Actions; HOMER1 is a member of the homer family of dendritic proteins.
