Description
Product Characteristics: WISP-2 is a member of the connective tissue growth factor/cysteine-rich 61/nephroblastoma overexpressed (nov) (CCN) family and is upregulated in the mouse mammary epithelial cell line C57MG transformed by Wnt-1 and in several non-invasive human breast tumor cell lines. WISP-2 expression is enhanced by important modulators of human breast cancer cell proliferation such as estrogen, progesterone and epidermal growth factor (EGF) in MCF-7 cells. These effects, inhibited by appropriate antagonists, indicate that steroids and growth factor-induced upregulation of WISP-2 may be mediated through receptors. WISP2 gene may be downstream in the WNT1 signaling pathway that is relevant to malignant transformation. Its expression in colon tumors is reduced while the other two WISP members are overexpressed in colon tumors. It is expressed at high levels in bone tissue, and may play an important role in modulating bone turnover.
Target Information: This gene encodes a member of the WNT1 inducible signaling pathway (WISP) protein subfamily, which belongs to the connective tissue growth factor (CTGF) family. WNT1 is a member of a family of cysteine-rich, glycosylated signaling proteins that mediate diverse developmental processes. The CTGF family members are characterized by four conserved cysteine-rich domains: insulin-like growth factor-binding domain, von Willebrand factor type C module, thrombospondin domain and C-terminal cystine knot-like (CT) domain. The encoded protein lacks the CT domain which is implicated in dimerization and heparin binding. It is 72% identical to the mouse protein at the amino acid level. This gene may be downstream in the WNT1 signaling pathway that is relevant to malignant transformation. Its expression in colon tumors is reduced while the other two WISP members are overexpressed in colon tumors. It is expressed at high levels in bone tissue, and may play an important role in modulating bone turnover. [provided by RefSeq, Jul 2008]
