Functioni

Transcription factor that regulates the expression of genes with essential roles in cell differentiation, proliferation and survival. Binds to symmetrical DNA sequences (E-boxes) (5'-CACGTG-3') found in the promoters of target genes, such as BCL2 and tyrosinase (TYR). Plays an important role in melanocyte development by regulating the expression of tyrosinase (TYR) and tyrosinase-related protein 1 (TYRP1). Plays a critical role in the differentiation of various cell types, such as neural crest-derived melanocytes, mast cells, osteoclasts and optic cup-derived retinal pigment epithelium By similarity.

Involvement in diseasei

Osteopetrotic rat of unknown genetic defect microphthalmia-blanc (mib) has been described whose skeletal sclerosis improves dramatically with age and that is associated with pigmentation defects. Mib at the homozygous state shows absence of skin and fur pigmentation, small eyes, and defects of incisor tooth eruption.
