    Adaptins are major structural components of heterotetrameric protein complexes called adaptors, which are essential in intracellular receptor transport via clathrin-coated vesicles. beta-adaptins constitute one of three known classes (alpha, beta, gamma) of adaptins, including beta and beta' subtypes. We previously cloned the human beta'-adaptin gene (BAM22) (GDB symbol, ADTB1) from chromosome 22q12 and proposed its involvement in the development of meningiomas. Here we describe the genomic organization of this gene, which consists of 22 exons spanning over approximately 100 kb. We also report results from point mutation screening of 7 randomly chosen exons analyzed in 110 sporadic meningiomas. As part of the genomic characterization of the BAM22 locus, we sequenced 40 kb covering exons 1-4 and 12 kb upstream from the start of gene transcription. Analysis of the sequence suggests that the BAM22 gene has a CG-rich promoter.
