OSTP_HUMAN - dbPTM
OSTP_HUMAN - PTM Information in dbPTM
Basic Information of Protein
UniProt ID OSTP_HUMAN
UniProt AC P10451
Protein Name Osteopontin
Gene Name SPP1
Organism Homo sapiens (Human).
Sequence Length 314
Subcellular Localization Secreted.
Protein Description Binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction.; Acts as a cytokine involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10 and is essential in the pathway that leads to type I immunity..
