14-3-3 sigma(SFN)antibody
Cat.#: 5209-1
Rabbit Monoclonal Antibody
Clone ID: EPR5872
Swiss Prot: P31947
Mol Weight: 28kDa
Size: 100ul
Description
14-3-3 proteins are composed of a highly conserved multigene family of small acidic proteins. Responsive to DNA damage, 14-3-3 sigma expression is induced in a p53-dependent manner. 14-3-3 sigma sequesters cyclin B1-CDC2 complex in cytoplasm, and prevents its entry into nucleus resulting in G2/M cell cycle arrest. Furthermore, 14-3-3 sigma can link to CDK2 and CDK4 and block the cell cycle entry. Thus, 14-3-3 sigma acts as a negative regulator of cell cycle progression and is linked to cancer (1). A keratinocyte-releasable form of 14-3-3 sigma is a potent MMP-1-stimulatory factor in dermal fibroblasts. When it is released from keratinocytes, it induces the expression of MMP1, MMP3, MMP8 and MMP24 in fibroblasts through the p38 mitogen-activated protein kinase (MAPK) signaling pathway (2).
