M-phase-specific PLK1-interacting protein (TTD non-photosensitive 1 protein) is a protein that in humans is encoded by the MPLKIP gene (previously known as C7orf11). Patients with an inherited defect in both alleles of the gene suffer from trichothiodystrophy (TTD) a disease hallmarked by brittle hair and nails and usually by developmental difficulties as well.
