Native GDNF, a disulfide-linked homodimeric glycoprotein, is a novel member of the TGF-beta superfamily. Rat GDNF cDNA encodes a 211 amino acid residue prepropeptide that is processed to yield a dimeric protein composed of two 134 amino acid residue subunits. The GDNF sequence contains two potential glycosylation sites and insect cell-expressed recombinant rat GDNF proteins are glycosylated. Mature rat and human GDNF exhibit approximately 93% amino acid sequence identity and show considerable species cross-reactivity. Cells known to express GDNF include Sertoli cells, type 1 astrocytes, Schwann cells, neurons, pinealocytes and skeletal muscle cells.
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. |
