The 230-kDa bullous pemphigoid antigen is a hemidesmosomal protein of the cutaneous basement membrane zone. The primary sequences deduced from full-length human cDNAs predict that this molecule consists of a central rod region and flanking globular domains. To get insight into regulation of the 230-kDa bullous pemphigoid antigen gene (BPAG1), and to evaluate evolutionary conservation of the amino-terminus of the protein, we screened a mouse genomic DNA library with a 0.3-kb cDNA corresponding to the 5' end of the human 230-kDa bullous pemphigoid antigen cDNA. A positive clone was isolated, and Southern analysis of the clone with the 0.3-kb cDNA allowed isolation of a 3.0-kb Hind III fragment containing the 5' end of the coding sequence. Alignment of the sequences of this subclone and human BPAG1 sequences revealed that this fragment contained 2466 bp of 5'- flanking DNA, upstream from the ATG translation initiation site, and 258 bp of translatable sequences that encode a putative polypeptide of 86 amino acids at the amino-terminus of the protein. This deduced polypeptide showed 91% homology with the corresponding human sequence. The TATAAA and CCAAT consensus sequences, as well as several putativecis-regulatory elements, were identified in the 5'-flanking region of the mouse DNA. To test the functional promoter activity of the 5'-flanking DNA, three mouse BPAG1 promoter/CAT reporter gene constructs, with the promoter segments spanning from -1133, -525, and -213 to -1, were developed. Transient transfections of mouse transformed keratinocytes (Pam 212 cells) with these constructs revealed clearly detectable CAT activities, indicating that the 5'-flanking region contains a functional promoter. Furthermore, these experiments suggested that the upstream sequences contain upregulatory elements, as well as elements that confer, at least in part, tissue specificity to the expression of the mouse 230-kDa BPA gene.
