The HEAT repeat domain is a protein domain found in a number of cytoplasmic proteins including the four that the give rise to the acronym HEAT (Huntingtin, elongation factor 3 (EF3), protein phosphatase 2A (PP2A), and the yeast PI3-kinase TOR1).[2] HEAT repeats form a rod-like helical structures which are involved in intracellular transport.
