Nuclear bone morphogenetic protein 2 (nBMP2) is a nuclear variant of the secreted growth factor BMP2. Experiments in nBmp2NLStm mutant mice, which lack nBMP2 in the nucleus, have shown that nBMP2 affects intracellular calcium transport in skeletal muscle and hippocampal neurons. The objective of this study was to determine whether nBMP2 affects the immune system, since activation of lymphocytes and other immune cells depends on intracellular calcium transport. We found that spleens in nBmp2NLStm mutant mice were 24% smaller than in wild type mice. The white pulp of the spleen contains many immune cells, particularly B and T lymphocytes and …

Bone morphogenetic protein 2 (BMP2) is a secreted growth factor that is essential for proper embryonic development and proliferation. Our laboratory discovered a nuclear variant of BMP2 (nBMP2) which is produced when translation is initiated at an alternative start codon within the BMP2 gene. When translation occurs at the downstream start codon, the resulting protein lacks the ER signal peptide, thereby allowing cytoplasmic translation and nuclear localization. Our aim is to distinguish the role of this nuclear localized variant from secreted BMP2. Overexpression of nBMP2 in HEK293 and HT29 cell lines resulted in a higher percentage of cells in proliferative …
