Tubulin polymerization-promoting protein is a protein that in humans is encoded by the TPPP gene.^{[3][4][5][6][7]}

This protein has been linked to multiple sclerosis myelin lesions and CSF abnormalities in multiple sclerosis patients.^[8]

This has also been linked to Parkinson's and Alsheimers Disease^[9][10]
