SPARC - secreted protein acidic and cysteine rich Gene
Also Known as ON; ONT; OI17; BM-40
Species: Homo sapiens
About SPARC
This gene has 9 transcripts (splice variants), 204 orthologues, 1 paralogue and is associated with 3 phenotypes. Broad expression in fat (RPKM 883.5), placenta (RPKM 823.4) and 20 other tissues.
Summary
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]
