TM2 Domain Containing Protein 2 (TM2D2)

TM2D2 contains a structural module related to that of the seven transmembrane domain G protein-coupled receptor superfamily. This protein has sequence and structural similarities to the beta-amyloid binding protein (BBP), but, unlike BBP, it does not regulate a response to beta-amyloid peptide. This protein may have regulatory roles in cell death or proliferation signal cascades. This gene has multiple alternatively spliced transcript variants which encode two different isoforms.The deduced 214-amino acid protein contains several features of a G protein-coupled receptor, including 2 putative transmembrane domains in its C-terminal half, a DRY motif, and conserved cysteines and lysines. Northern blot analysis detected variable expression of a 1.35-kb BLP1 transcript in all human tissues examined.
