Biological Activity

[Description]:

DL-Tyrosine is an aromatic nonessential amino acid synthesized from the essential amino acid phenylalanine. DL-Tyrosine is a precursor for several important neurotransmitters (epinephrine, norepinephrine, dopamine)[1].

DNase II-dependent DNA digestion is required for DNA sensing by TLR9.

Nat. Commun. 6 , 5853, (2015)

DNase II digests DNA in endolysosomes. In the absence of DNase II, undigested DNA activates cytoplasmic DNA-sensing pathways. Little is known, however, about the role of DNase II in endolysosomal DNA ...
