[Elabscience]
特徴
- 背景：Human b-Nerve Growth Factor (b-NGF) was initially isolated in the mouse submandibular gland. It is composed of three non-covalently linked subunits α; b; and gamma; it exhibits all the biological activities ascribed to NGF. It is structurally related to BDNF; NT-3 and NT-4 and belongs to the cysteine-knot family of growth factors that assume stable dimeric structures. b-NGF is a neurotrophic factor that signals through its receptor b-NGF; and plays a crucial role in the development and preservation of the sensory and sympathetic nervous systems. b-NGF also acts as a growth and differentiation factor for B lymphocytes and enhances B-cell survival. These results suggest that b-NGF is a pleiotropic cytokine; which in addition to its neurotropic activities may have an important role in the regulation of the immune system. Human b-NGF shares 90% sequence similarity with mouse protein and shows cross-species reactivity.
