The distinction between graduate school and professional school is somewhat like the distinction between basic science and applied science; the differences lie in the focus. In graduate school, students focus primarily on mastering a particular field of study.
Protein deglycase DJ-1, also known as Parkinson disease protein 7, is a protein which in humans is encoded by the PARK7 gene.ARK7 belongs to the peptidase C56 family of proteins. The protein structures of human protein DJ-1, Escherichia coli chaperone Hsp31 and an Archaea protease are evolutionarily conserved.
The MTHFR nucleotide at position 677 in the gene has two possibilities: C (cytosine) or T (thymine). C at position 677 (leading to an alanine at amino acid 222) is the normal allele. The 677T allele (leading to a valine substitution at amino acid 222) encodes a thermolabile enzyme with reduced activity.
