BMP receptor signaling: transcriptional targets, regulation of signals, and signaling cross-talk

Cytokine Growth Factor Rev. 2005 Jun;16(3):251-63. doi: 10.1016/j.cytogfr.2005.01.009.


Bone morphogenetic proteins (BMPs), members of the transforming growth factor-beta (TGF-beta) superfamily, bind to two different serine/threonine kinase receptors, and mediate their signals through Smad-dependent and Smad-independent pathways. Receptor regulated-Smad (R-Smad) proteins specific for the BMP pathways interact with various proteins, including transcription factor Runx, and transmit specific signals in target cells. The recent development of DNA microarray techniques has allowed us to identify many BMP target genes. BMP signaling is modulated by various molecules, including inhibitory Smads (I-Smads). Moreover, recent findings have revealed that BMP pathways interact with other signaling pathways, and such signaling cross-talk plays pivotal roles in growth and differentiation of target cells.
