Description | A homodimeric protein consisting of two 134 amino acid non-glycosylated polypeptide chains corresponding to GDNF Source: E. coli Uniprot ID: Q07731 Amino Acid Sequence: SPDKQAAALP RRERNRQAAA ASPENSRGKG RRGQRGKNRG CVLTAIHLNV TDLGLGYETK EELIFRYCSG SCEAAETMYD KILKNLSRSR RLTSDKVGQA CCRPVAFDDD LSFLDDSLVY HILRKHSAKR CGCI |
Details of Functionality | GDNF protein is fully biologically active when compared to standard. Measured by its ability to support the survival and stimulate neurite outgrowth of dissociated chick embryonic dorsal root ganglia (DRG) neurons. The ED50 for this effect is typically 1 - 3 ng/mL |

The identification of dopaminergic neurons using Tyrosine Hydroxylase in Parkinson's research and LRRK2 Tyrosine hydroxylase (TH) is a crucial enzyme involved in the biosynthesis of dopamine, norepinephrine and epinephrine in the brain. Specifically, TH catalyzes the conversion of l-tyrosine to l-dihydroxyphenylalanine (l-dopa). The importance of t... Read full blog post. |
