  • Function
    Appears to regulate cell growth through interactions with the extracellular matrix and cytokines. Binds calcium and copper, several types of collagen, albumin, thrombospondin, PDGF and cell membranes. There are two calcium binding sites; an acidic domain that binds 5 to 8 Ca(2+) with a low affinity and an EF-hand loop that binds a Ca(2+) ion with a high affinity.
  • Sequence similarities
    Belongs to the SPARC family.
    Contains 1 EF-hand domain.
    Contains 1 follistatin-like domain.
    Contains 1 Kazal-like domain.
  • Developmental stage
    Expressed at high levels in tissues undergoing morphogenesis, remodeling and wound repair.
  • Cellular localization
    Secreted > extracellular space > extracellular matrix > basement membrane. In or around the basement membrane.
