설명

일반 설명

Neuroserpin is an inhibitory serpin that is expressed predominantly in central nervous system. Although the physiological target of neuroserpin is still unclear, cumulative evidence suggest that it plays an important role in controlling proteolytic degradation of extracellular matrix (ECM) during synaptogenesis and the subsequent development of neuronal plasticity. In the adult brain, neuroserpin is secreted from the growth cones of neurons in areas where synaptic changes are associated with learning and memory, i.e. cerebral cortex, hippocampus, and amygdala. The neuroprotective role of neuroserpin has been demonstrated in transgenic mice lacking neuroserpin expression. The deficiency of neuroserpin in these mice was associated with motor neuron disease characterized by axonal degradation. In humans, defects in neuroserpin, caused by point mutations in the neuroserpin gene, underlie a hereditary disorder called the familial encephalopathy with neuroserpin inclusion bodies (FENIB). Recombinant human neuroserpin is a 44.6 kDa non-glycosylated protein containing 394 amino-acid residues.

생화학적/생리학적 작용

SERPINI1, also known as neuroserpin, is a serine proteinase inhibitor that belongs to the serpin superfamily. It inhibits plasminogen activators and plasmin but not thrombin and is predominantly secreted by axons in the brain. Neuroserpin may be involved in the regulation of axonal growth and the development of synaptic plasticity. Defects in this gene cause familial encephalopathy with neuroserpin inclusion bodies (FENIB), which is characterized by the accumulation of mutant neuroserpin polymers. The protein may have a role in colorectal cancer.

재구성

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
