Microphthalmia-associated transcription factor (Mitf) is a basic helix-loop-helix leucine zipper transcription factor involved in melanocyte[1] and osteoclast development.[2]

Contents

Clinical significance

It can be associated with Tietz syndrome[3] and Waardenburg syndrome type IIa.[4]

Target genes

Mitf recognizes E-box (CAYRTG) and M-box (TCAYRTG or CAYRTGA) sequences in the promoter regions of target genes. Known target genes (confirmed by at least two independent sources) of this transcription factor include,

ACP5[5][6]

BCL2[6][7]

BEST1[6][8]

BIRC7[6][9]

CDK2[6][10]

CLCN7[6][11]

DCT[6][12]

EDNRB[6][13]

GPNMB[6][14]

GPR143[6][15]

MC1R[6][16]

MLANA[6][17]

OSTM1[6][11]

RAB27A[6][18]

SILV[6][17]

SLC45A2[6][19]

TBX2[6][20]

TRPM1[6][21]

TYR[6][22]

TYRP1[6][23]

Additional genes identified by a microarray study (which confirmed the above targets) include the following,[6]

MBP TNFRSF14 IRF4 RBM35A
PLA1A APOLD1 KCNN2 INPP4B
CAPN3 LGALS3 GREB1 FRMD4B

Interactions

Microphthalmia-associated transcription factor has been shown to interact with PATZ1,[24] PIAS3,[25] TFE3,[26][27] UBE2I[28] and Lymphoid enhancer-binding factor 1.[12]
