Bone mineral density (BMD) is a highly heritable predictor of osteoporotic fracture. GWAS have identified hundreds of loci influencing BMD, but few have been functionally analyzed. In this study, we show that SNPs within a BMD locus on chromosome 14q32.32 alter splicing and expression of PAR-1a/microtubule affinity regulating kinase 3 (MARK3), a conserved serine/threonine kinase known to regulate bioenergetics, cell division, and polarity. Mice lackingMark3either globally or selectively in osteoblasts have increased bone mass at maturity. RNA profiling fromMark3-deficient osteoblasts suggested changes in the expression of components of the Notch signaling pathway.Mark3-deficient osteoblasts exhibited greater matrix mineralization compared with controls that was accompanied by reducedJag1/Hes1expression and diminished downstream JNK signaling. Overexpression ofJag1inMark3-deficient osteoblasts both in vitro and in vivo normalized mineralization capacity and bone mass, respectively. Together, these findings reveal a mechanism whereby genetically regulated alterations inMark3expression perturb cell signaling in osteoblasts to influence bone mass.
