Western Blot (WB)

(TPT1 Antibody (Center) western blot analysis in LNCaP cell line lysates (35ug/lane).This demonstrates the TPT1 antibody detected the TPT1 protein (arrow).)

Immunohistochemistry (IHC)

(Formalin-fixed and paraffin-embedded human hepatocarcinoma reacted with TPT1 Antibody (Center), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.)

Flow Cytometry (FC/FACS)

(TPT1 Antibody (Center) flow cytometric analysis of Jurkat cells (bottom histogram) compared to a negative control cell (top histogram).FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.)

Uniprot Description

TPT1: a novel heat shock protein with antiapoptotic and chaperone-like activity. Its levels are highly regulated in response to various cellular stimuli and stresses. Downregulated in response to proapoptotic treatments that induce Ca(++) stress, in a PKR-dependent manner. Colocalizes with CHFR to the mitotic spindle. Appears to be involved in calcium binding and microtubule stabilization. Its exosomal secretion is induced following DNA damage. Interacts with MCL1 and STEAP3, a p53-inducible transmembrane protein that facilitates the exosomal secretion of TPT1. Secreted TPT1 acts as a histamine-releasing factor, participates in inflammatory responses by inducing the release of histamine, and may play a role in tumor reversion. May play a direct role in placental calcium transport. Phosphorylation by Plk may decrease its microtubule-stabilizing activity and promote microtubule dynamics following metaphase. Critical for peripheral T cell maintenance and TCR-mediated cell proliferation.
