Homeobox protein MSX-2 is a protein that in humans is encoded by the MSX2 gene. [4] [5] [6]

Contents

Function

This gene encodes a member of the muscle segment homeobox gene family. The encoded protein is a transcriptional repressor whose normal activity may establish a balance between survival and apoptosis of neural crest-derived cells required for proper craniofacial morphogenesis. The encoded protein may also have a role in promoting cell growth under certain conditions and may be an important target for the RAS signaling pathways. Mutations in this gene are associated with parietal foramina 1 and craniosynostosis type 2. [6] Msx2 is a homeobox gene localized on human chromosome 5 that encodes a transcription repressor and activator (MSX-2) responsible for craniofacial and limb-bud development. Cells will express msx2 when exposed to signaling molecules BMP-2 and BMP-4 in situ. [7] Expression of msx2 leads to the proliferation, migration and osteogenic differentiation of neural crest cells during embryogenesis and bone fracture. [8] It is well documented that expression of cell-cell adhesion molecules such as E-cadherins will promote structural integrity and an epithelial arrangement of cells, while expression of N-cadherin and vimentin promote mesenchymal arrangement and cell migration. [9] [10] Msx2 downregulates E-cadherins and upregulates N-cadherin and vimentin which indicates its role in inducing epithelial mesenchymal transition (EMT). Germline knockout mice have been created for this gene (Msx2 +/-) in order to examine functional loss. [11] Clinical studies on craniosynostosis, or the premature fusion of cranial structures, have shown the condition to be genetically linked to mutation in the msx2 homeobox gene. [12]

Interactions

Msh homeobox 2 has been shown to interact with DLX5, [13] DLX2 [13] and MSX1. [13]

Homeobox protein MSX-1, is a protein that in humans is encoded by the MSX1 gene. MSX1 transcripts are not only found in thyrotrope-derived TSH cells, but also in the TtT97 thyrotropic tumor, which is a well differentiated hyperplastic tissue that produces both TSHß- and a-subunits and is responsive to thyroid hormone. MSX1 is also expressed in highly differentiated pituitary cells which until recently was thought to be expressed exclusively during embryogenesis. There is a highly conserved structural organization of the members of the MSX family of genes and their abundant expression at sites of inductive cell–cell interactions in the embryo suggest that they have a pivotal role during early development.

Transcription factor Sp7, also called osterix (Osx), is a protein that in humans is encoded by the SP7 gene. It is a member of the Sp family of zinc-finger transcription factors It is highly conserved among bone-forming vertebrate species It plays a major role, along with Runx2 and Dlx5 in driving the differentiation of mesenchymal precursor cells into osteoblasts and eventually osteocytes. Sp7 also plays a regulatory role by inhibiting chondrocyte differentiation maintaining the balance between differentiation of mesenchymal precursor cells into ossified bone or cartilage. Mutations of this gene have been associated with multiple dysfunctional bone phenotypes in vertebrates. During development, a mouse embryo model with Sp7 expression knocked out had no formation of bone tissue. Through the use of GWAS studies, the Sp7 locus in humans has been strongly associated with bone mass density. In addition there is significant genetic evidence for its role in diseases such as Osteogenesis imperfecta (OI).
