Descriptions:C-C Motif Chemokine Ligand 4 (CCL4) is a 7.66 kDa cytokine with 69 amino acid residues. CCL4, also named macrophage inflammatory protein-1β (MIP-1β), is mainly secreted from neutrophils, monocytes, B cells, T cells, fibroblasts, endothelial cells and epithelial cells. CCL4 recruits various immune cells like natural killer cells, monocytes, and neutrophils when CCL4 binds to CCR5. In addition, CCL4 mediates lymphocyte adhesion by Rac1 /Cdc42 signaling pathway and plays critical roles in different biological functions like maintenance of cell polarity, regulation of calcium ion transport and response to viruses.

Descriptions:Fms-related tyrosine kinase-3 ligand (Flt-3 Ligand) is a protein which is encoded by the FLT3LG gene in human. As an important regulator of hematopoiesis, Flt-3 ligand has a tyrosine-protein kinase activity that stimulate the proliferation of hematopoietic progenitor cells of both lymphoid and myeloid origin. Flt-3 ligand can synergistically increase the proliferation of immature progenitors with other cytokines such as GM-CSF, G-CSF, IL-3, EPO, IL-11, IL-12, IL-6 or TPO. Flt-3 ligand is expressed by a variety of hematopoietic progenitor cells including immature hematopoietic and

Descriptions:Bone Morphogenetic Protein-2 (BMP-2) is an extracellular multifunctional signaling cytokine that is also a member of the TGF-β family. BMP-2 can bind with the TGF-β receptor to active SMAD protein signal transduction. Moreover, it engages in the path of signals such as Wnt and Notch. BMP-2 plays an essential role in the growth of hard bones and cartilage and involved in the differentiation of osteoblasts.

Descriptions:Bone morphogenetic protein-2 (BMP-2) is a kind of bone growth regulator, belonging to protein transforming growth factor-β(TGF-β) superfamily. BMP-2 protein is involved in hedgehog pathway, TGF-β signaling pathway and cytokine-cytokine receptor interaction. BMP-2 and BMP-7 are osteogenic BMP, which have been proved to be effective in inducing osteoblast differentiation in many cell types. The active form of BMP-2 can be composed of dimers of two identical proteins or heterodimers of two related bone morphogenetic proteins.

Descriptions:NADP phosphatase (NADPase) is mainly present in plant tissues and is the only enzyme in organisms that catalyzes the degradation of NADP+ to NAD+. Together with NADK, it regulates the balance between NAD and NADP.

Descriptions:GDF-3 (previously called Vgr-2) is a TGF-beta superfamily member belonging to the growth/differentiation factor family. GDF-3 is expressed in undifferentiated embryonic stem (ES) cells, white adipose tissue and the brain. The 366 amino acid (aa) mouse GDF-3 contains a 22 aa signal sequence, a 230 aa propeptide and a 114 aa mature protein that contains one potential N-glycosylation site. The mature region contains a cysteine-knot structure that is conserved throughout family members. However, it lacks the fourth cysteine which is responsible for the formation of an inter-molecular disulfide bond, so GDF-3 may exist as a non-covalent homodimer. Mature human GDF-3 shares 83%, 83% aa sequence identity with mouse and rat GDF-3. Most of GDF-3 is present as the uncleaved prepro form. The uncleaved and the mature forms both appear to have activity, but that activity may differ. All forms can oppose BMPs. In ES cells, inhibition of BMP2 signaling by GDF-3 maintains pluripotency. GDF-3 also influences early cell fate decisions; for example, deletion of mouse GDF-3 produces defects in the anterior visceral endoderm of the pre-gastrulation embryo. GDF-3 cooperates with GDF-1 in embryogenesis, and the mature protein has nodal-like activity. Although GDF family members signal through BMP receptors (ALK1, 2, 3 and 6), which activate Smads 1, 5 and 8, GDF-3 signaling through ALK4 and ALK7, which activate Smads 2 and 3, has also been reported. In adipocytes, GDF-3 is induced by a high fat diet, promoting adipogenesis and obesity.
