MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a noncollagenous extracellular matrix (ECM) protein. It consists of five identical glycoprotein subunits, each with EGF-like and calcium-binding (thrombospondin-like) domains. Oligomerization results from formation of a five-stranded coiled coil and disulfides. Binding to other ECM proteins such as collagen appears to depend on divalent cations. Contraction or expansion of a 5 aa aspartate repeat and other mutations can cause pseudochondroplasia (PSACH) and multiple epiphyseal dysplasia (MED). [provided by RefSeq, Jul 2016]
PHENOTYPE: Mice homozygous for a targeted null mutation are indistinguishable from controls. Mice homozygous for a knockin allele with two point mutations exhibit short limb dwarfism, osteoarthritis, abnormal chondrocytes, mild myopathy, and abnormal tendon morphology and stiffness.
