HSF1 Antibody (744509)

HSF1 was detected in perfusion fixed frozen sections of mouse testis using Rat Anti-Mouse HSF1 Monoclonal Antibody (Catalog # MAB7130) at 25 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to nuclei of spermatocytes. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Background

Heat Shock Factor 1 (HSF1) is a 75-80 kDa constitutively expressed protein that functions as a transcriptional regulator under heat shock conditions. Heat stress induces the serine hyperphosphorylation, sumoylation, trimerization, and translocation of HSF1 to the nucleus. Nuclear HSF1 binds to heat shock elements (HSE) and promotes the transcription of genes important in cell protection from heat stress. Mouse HSF1 contains a DNA binding domain (aa 16-120), two hydrophobic oligomerization motifs (aa 137-212 and aa 378-407), a regulatory domain (aa 221-310), and a transactivation domain (aa 367-525). Alternate splicing of mouse HSF1 generates a short isoform that lacks 22 amino acids of the transactivation domain. Within aa 124-247, mouse HSF1 shares 94% and 99% aa sequence identity with human and rat HSF1, respectively.
