Adipocyte Plasma Membrane Associated Protein (APMAP)

It is proposed that CMAP expression is correlated with the metastatic potential of malignant tumors. Like murine CMAP, the human CMAP gene is constructed from four divided exons, all of which encode the functional domains of the putative translational product. Based on the computational analysis, a novel gene weakly similar to the plant strictosidine synthase, named BSCv (HGMW-approved symbol C20orf3), was identified on the opposite allele at a distance of a few kilobases from the human CMAP gene. In between human CMAP and the BSCv gene, there is a unique tandem repeat sequence. CpG-rich island characteristics and GC-box features normally observed in housekeeping genes were not seen around exon 1 of the CMAP gene, reflecting the restricted expression of CMAP in hematopoietic cells.
