MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a cysteine-rich acidic matrix-associated protein. The encoded protein is required for the collagen in bone to become calcified but is also involved in extracellular matrix synthesis and promotion of changes to cell shape. The gene product has been associated with tumor suppression but has also been correlated with metastasis based on changes to cell shape which can promote tumor cell invasion. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2015]
PHENOTYPE: Homozygotes for targeted null mutations exhibit cataracts, reduced skin collagen content, accelerated wound closure, osteopenia associated with reduced bone remodeling, and increased growth of implanted tumors. [provided by MGI curators]
