HEAT Repeat Containing Protein 7B1 (HEATR7B1)

HEATR7B1 Contains 14 HEAT repeats. The HEAT repeat is a tandemly repeated, 37-47 amino acid long module occurring in a number of cytoplasmic proteins, including the four name-giving proteins huntingtin, elongation factor 3 (EF3), the 65 Kd alpha regulatory subunit of protein phosphatase 2A (PP2A) and the yeast PI3-kinase TOR1. Arrays of HEAT repeats consists of 3 to 36 units forming a rod-like helical structure and appear to function as protein-protein interaction surfaces. It has been noted that many HEAT repeat-containing proteins are involved in intracellular transport processes.
HEAT repeats correspond to tandemly arranged curlicue-like structures that appear to serve as flexible scaffolding on which other components can assemble.
