Summary: Enables identical protein binding activity and low-density lipoprotein particle receptor binding activity. Involved in phagocytosis and positive regulation of skeletal muscle acetylcholine-gated channel clustering. Acts upstream of or within protein folding and protein localization to cell surface. Located in plasma membrane. Is expressed in several structures, including 4-cell stage embryo; genitourinary system; hemolymphoid system; liver; and ventricular layer. Human ortholog(s) of this gene implicated in osteogenesis imperfecta type 20. Orthologous to human MESD (mesoderm development LRP chaperone). [provided by Alliance of Genome Resources, Dec 2024]

Mescd2 binds to Lrp4 and regulates Lrp4 surface expression in myotubes.
Title: Mesdc2 plays a key role in cell-surface expression of Lrp4 and postsynaptic specialization in myotubes.
Mesd C-terminal region constitutes the major LRP5/6-binding domain, and that Mesd protein and its C-terminal region peptide have a potential therapeutic value in cancer
Title: The C-terminal region Mesd peptide mimics full-length Mesd and acts as an inhibitor of Wnt/β-catenin signaling in cancer cells.
The region 45-184 of MESD is essential and sufficient to act as a molecular chaperone for the low-density lipoprotein receptor (LDLR) family.
Title: The structure of MESD45-184 brings light into the mechanism of LDLR family folding.
Mesd not only blocks binding of Dickkopf (DKK)-1 and sclerostin proteins to low-density lipoprotein receptor-related protein (LRP)5 and LRP6 but also inhibits Wnt/beta-catenin signaling in LRP5- or LRP6- expressing cancer cells.
Title: Mesd is a universal inhibitor of Wnt coreceptors LRP5 and LRP6 and blocks Wnt/beta-catenin signaling in cancer cells.
Secondary structure prediction using chemical shift data indicates that MESD(12-155) contains four a-helices and five b-sheets.
Title: A complete NMR spectral assignment of the conserved region of the MESD protein, MESD(12-155).
Functional analyses of the Lrp6 rs mutant showed decreased targeting to plasma membrane because of reduced interaction with Mesoderm development (Mesd), a chaperone for Lrp6, leading to impaired Wnt/beta-catenin signaling
Title: Lrp6 hypomorphic mutation affects bone mass through bone resorption in mice and impairs interaction with Mesd.
We show that MESD contains a central folded domain flanked by unstructured regions required to facilitate maturation of LRP6. Enforced expression of human MESD promotes the secretion of soluble minireceptors derived from LRP6.
Title: Requirement for natively unstructured regions of mesoderm development candidate 2 in promoting low-density lipoprotein receptor-related protein 6 maturation.
Together our results show that in addition to serving as a folding chaperone, Mesd can function as a receptor antagonist by inhibiting ligand binding to mature LRP6.
Title: Mesd binds to mature LDL-receptor-related protein-6 and antagonizes ligand binding.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
