SPARC/Osteonectin active protein
Human SPARC/Osteonectin
NCBI and Uniprot Product Information
NCBI Description
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.

Uniprot Description
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 Ca2+ with a low affinity and an EF-hand loop that binds a Ca2+ ion with a high affinity.
Subcellular location: Secreted › extracellular space › extracellular matrix › basement membrane. Note: In or around the basement membrane. Ref.10 Ref.11 Ref.12 Ref.13
Developmental stage: Expressed at high levels in tissues undergoing morphogenesis, remodeling and wound repair.
Sequence similarities: Belongs to the SPARC family.Contains 1 EF-hand domain.Contains 1 follistatin-like domain.Contains 1 Kazal-like domain.
Sequence caution: The sequence AAA60993.1 differs from that shown. Reason: Contaminating sequence. Sequence of unknown origin in the C-terminal part.

It is sometimes possible for the material contained within the vial of "SPARC/Osteonectin, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
