It is designed for detection and analysis of the Phosphorylation [Ser326] post-translational modification across research applications.\u003c\/p\u003e\n\u003cp\u003eHeat shock gene transcription is regulated by a family of heat shock factors (HSFs), transcriptional activators that bind to heat shock response elements (HSEs) located upstream of all heat shock genes. Vertebrate cells contain four HSF proteins: HSF1, 2 and 4 are ubiquitous, while HSF3 has only been characterized in avian species. HSF1 induces heat shock gene transcription in response to heat, heavy metals, and oxidative agents, while HSF2 is involved in spermatogenesis and erythroid cell development. HSF3 and HSF4 show overlapping functions with HSF1 and HSF2. The inactive form of HSF1 exists as a monomer that localizes to both the cytoplasm and nucleus, but does not bind DNA. In response to stress, HSF1 becomes phosphorylated, forms homotrimers, binds DNA and activates heat shock gene transcription. HSF1 activity is positively regulated by phosphorylation of Ser419 by PLK1, which enhances nuclear translocation, and phosphorylation of Ser230 by CaMKII, which enhances transactivation. Alternatively, HSF1 activity is repressed by phosphorylation of serines at 303 and 307 by GSK3 and ERK1, respectively, which leads to binding of 14-3-3 protein and sequestration of HSF1 in the cytoplasm.\u003c\/p\u003e\n\u003ch2\u003eValidated Applications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eWestern Blot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRecommended Dilution\u003c\/th\u003e\n\u003ctd\u003eWB 1:2000-1:5000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost\u003c\/th\u003e\n\u003ctd\u003eRabbit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClonality\u003c\/th\u003e\n\u003ctd\u003eRecombinant Monoclonal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIsotype\u003c\/th\u003e\n\u003ctd\u003eIgG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReactivity\u003c\/th\u003e\n\u003ctd\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConjugate\u003c\/th\u003e\n\u003ctd\u003eUnconjugated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePurification\u003c\/th\u003e\n\u003ctd\u003eProtein A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Weight\u003c\/th\u003e\n\u003ctd\u003eCalculated: 57 kDa | Observed: 82 kDa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eImmunogen \/ Antigen\u003c\/h2\u003e\n\u003cp\u003epolypeptide\u003c\/p\u003e\n\u003ch2\u003eReactivity Notes\u003c\/h2\u003e\n\u003cp\u003eThis antibody shows reactivity with Human.
