IGF2BP3 Rabbit anti-Human, Mouse, Polyclonal, Proteintech

Description

Both isoforms (64 kDa and 22 kDa) of IGFBP3 can be recognized by this antibody. IGFBP3 is nuclear and cytoplasmic in staining.

Insulin-like growth factor-II messenger RNA (mRNA)-binding protein-3 (IMP-3), also known as K homology domain-containing protein overexpressed in cancer (KOC) and L523S, is a member of the insulin-like growth factor-II mRNA-binding protein family and is expressed during embryogenesis and in some maligcies. IMP-3 is expressed in maligt melanoma but not in benign nevi, even when dysplastic features are present; IMP-3 is expressed in a significantly higher proportion of melanomas than Spitz nevi; and IMP-3 is expressed in metastatic melanomas significantly more than in thin melanomas. IMP-3 appears to be involved in the progression of maligt melanoma and may play an important role in the regulation of the biologic behavior of this tumor.
