c-maf is the cellular counterpart of oncogenic v-maf that belongs to the family of basic region leucine zipper domain transcription factors. The leucine-zipper domain is involved in the interaction with LRPICD. There are two forms of human c-maf mRNA, c-maf-long and c-maf-short. It is identified in the genome of the acute transforming avian retrovirus AS42. c-maf targets are IL-4 in Th2 cells, the crystalline genes in lens fiber cells, insulin gene in islet, p53 and L7 where it exerts its transcriptional role through binding to a Maf recognition element (MARE). It regulates Th2 differentiation and lineage-specific hematopoiesis. c-maf is a transcription factor for IL-10 gene expression in LPS-activated macrophages. Chromosomal aberration involving maf is found in some forms of multiple myeloma. It is expressed in myeloma cell lines and resting monocytes/macrophages.
