Chromosomal mapping of the human and mouse homologues of two new members of the AP-2 family of transcription factors

Genomics. 1996 Jul 1;35(1):262-4. doi: 10.1006/geno.1996.0351.


The AP-2 transcription factor has been shown to play an important role in the development of tissues of ectodermal origin and has also been implicated in mammary oncogenesis. It has recently been found that AP-2 is encoded by a family of related genes, AP-2alpha, AP-2beta, and AP-2gamma. As a further step in understanding the role each of these genes has in development, we have used fluorescence in situ hybridization to map the chromosomal locations of the mouse and human homologues of the newly isolated AP-2beta and AP-2gamma genes. Tcfap2b and Tcfap2c map to mouse chromosomes 1A2-4 and 2H3-4, respectively, while TFAP2B and TFAP2C map to human chromosomes 6p12 and 20q13.2, the latter being a region that is frequently amplified in breast carcinoma.
