| Short Name | MafA |
| description | Maf transcription factors form a distinct family of the basic leucine zipper (bZip) transcription factors. The Maf family is divided into two subclasses, large Mafs (c-maf, mafB, and mafA/L-maf, nrl) and small Mafs (MafF, MafK and MafG). Both subclasses contain leucine-zipper motifs, which allow homodimerisation as well as heterodimerisation with a variety of other bZip proteins. In contrast to the small Mafs, the large Maf proteins contain a transactivator domain in their amino terminus []. The small Maf proteins might contribute to oncogenic processes by participating in antioxidant responses, while large Maf proteins have been directly implicated in carcinogenesis []. This entry represents MafA. MafA plays a critical role in the regulation of crystalline genes and lens development [, ]. It also binds the insulin enhancer element RIPE3b and regulates the insulin gene transcription [, , ]. |
