Rabbit Anti-IGFBP5/FITC Conjugated antibody
background:
IGFBP5 is one of a family of proteins that bind to insulin-like growth factors (IGFs). IGFBP5 is a multifunctional protein which acts not only as a traditional binding protein but also functions as a growth factor independent of IGFs to stimulate bone formation. Currently there are seven named IGF-BPs that form high affinity complexes with both IGFI and IGFII. IGFBP5 is the major IGF-binding protein present in bone tissue and helps potentiate the action of IGFI on smooth muscle cells, fibroblasts or osteoblasts. Data shows that IGFBP5 acts as a growth inhibitor and pro-apoptotic agent in breast cancer cells. IGFBP5 overexpressing mice show an increase in neonatal mortality, reduced female fertility, whole-body growth inhibition and retarded muscle development.
Function:
IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
Subcellular Location:
Secreted.
Tissue Specificity:
Osteosarcoma, and at lower levels in liver, kidney and brain.
Similarity:
Contains 1 IGFBP N-terminal domain.
Contains 1 thyroglobulin type-1 domain.

生长因子和激素( Growth Factor and Hormones)
IGFBP5胰岛素样生长因子结合蛋白5(IGFBP-5)是一种可以与胰岛素样生长因子(IGFs)结合的分泌性蛋白,其通过IGFs调节细胞的生长、分化、凋亡、黏附和运动,IGFBP-5与IGFs结合可以调节IGFs与IGF-I型受体间的相互作用,改变其促有丝分裂效应、凋亡抑制效应和促细胞运动作用。
有人认为:由于造骨细胞能表达与IGF-1受体截然不同的IGFBP-5受体,IGFBP-5本身也是一种生长因子,能够不依赖IGF-I独立作用来调节骨代谢。
