Inoue et al. (1994) demonstrated that the US-2 element in the promoter of the human oxytocin receptor gene (OXTR; 167055) binds specifically nuclear proteins from human myometrium at parturition. Using the US-2 element in a yeast 1-hybrid system to screen a human myometrium cDNA library, Kimura et al. (1999) isolated a full-length cDNA encoding the homolog of chicken MafF. Human MAFF encodes a deduced 164-amino acid protein with a predicted molecular mass of 17.8 kD. Like other small MAF proteins (e.g., MAFG, 602020), it contains an extended leucine zipper structure and lacks an N-terminal transactivating domain. Northern blot analysis showed a strong 2.6-kb signal in mRNA from term myometrium and from kidney, but not from nonpregnant myometrium. The MAFF protein is also preferentially expressed in term myometrium. The authors concluded that MAFF plays a role in OXTR gene upregulation at term.
In their DNA sequence report of human chromosome 22, Dunham et al. (1999) located the MAFF gene on 22q12.2-q13.2.
