Fig. 8. Protein sequence comparison of the quail Mi protein with those of the chicken, human, and murine Mi and with the other TFE members. Numbers, amino acid positions in Mi. Boxes, conserved amino acids; dark gray boxes, shared amino acids; light gray boxes, amino acids with similar physicochemical character. Gaps (-) are introduced to allow maximal alignment. Accession numbers of the sequences used were as follows: chicken Mi, GenBank D88363 (35) ; murine Mi, GenBank Z23066; human MI, GenBank Z29678; human TFE3, EMBL 51330; human TFEB, GenBank M33782; rat TFEC, GenBank, L08812.
