Name :
Human MANF protein, biotinylated, recombinant

Description :
MANF (mesencephalic astrocyte-derived neurotrophic factor), also known as ARMET (arginine-rich protein mutated in early stage tumors) and ARP (arginine-rich protein), belongs to the ARMET family. The MANF gene is located on chromosome 3p21.1, a region that is frequently deleted in a variety of solid tumors. MANF is localized in the endoplasmic reticulum (ER) and golgi, and is also secreted. MANF protects rat embryonic nigral dopaminergic neurons and restores motor function in a rat model of Parkinson’s disease (PD), a movement disorder with characteristic degeneration of dopaminergic neurons. MANF is also known to inhibit cell proliferation and ER stress-induced cell death. The crystal structure shows that MANF consists of two domains, an amino-terminal saposin-like domain that may interact with lipids or membranes and be responsible for its neurotrophic activity, and a presumably unfolded carboxy-terminal domain that may protect cells against ER stress. MANF has also been identified as one of genes in the heart that can be induced and secreted in response to ER stresses such as ischemia. Circulating MANF may protect cardiac myocytes in an antocrine and paracrine manner. MANF is also upregulated in cerebral ischemia in rats and may have neuroprotective effects against cerebral ischemia. Human MANF is synthesized as a 179 amino acid precursor, which is processed to a mature form of 158 amino acids. Human MANF is 99% and 98% amino acid identical to rat and mouse MANF, respectively.
