Glutamine
Glutamine is the most abundant naturally occurring, nonessential amino acid in the human body, and one of the few amino acids that can directly cross the blood–brain barrier. Humans obtain glutamine through catabolism of proteins in foods they eat. In states where tissue is being built or repaired, like growth of babies, or healing from wounds or severe illness, glutamine becomes conditionally essential.
QRICH2
QRICH2 protein is 1663 amino acids long, and 10.9% of the amino acids are Glutamine (Q). 38% of the QRICH2 protein secondary structure is alpha-helix, 39% is beta-sheet and 13% is turning. The human tissue type with the highest level of QRICH2 expression is testis, and this result is confirmed by the Gene Expression Profile for mouse and dog too. The subcellular location of QRICH2 protein is in the nucleus. QRICH2 is a soluble protein, its average hydrophobicity is -0.5995. QRICH2 protein interact with a number of other proteins including SSSCA1, TSSC1, GAPDH, NUP98 and SNAI1.
