UniProt Protein Function: | 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.Protein type: Calcium-binding; Microtubule-bindingCellular Component: cytoplasm; extracellular space; multivesicular body; nucleoplasm; nucleus; tubulin complexMolecular Function: calcium ion binding; microtubule binding; transcription factor bindingBiological Process: cell differentiation; stem cell maintenance |
